Subject: [PATCH] wifi: ath: work around false-positive stringop-overread
warning
In a rare arm64 randconfig build, I got multiple warnings for ath11k
and ath12k:
In function 'ath11k_peer_assoc_h_ht',
inlined from 'ath11k_peer_assoc_prepare' at drivers/net/wireless/ath/ath11k/mac.c:2665:2:
drivers/net/wireless/ath/ath11k/mac.c:1709:13: error: 'ath11k_peer_assoc_h_ht_masked' reading 10 bytes from a region of size 0 [-Werror=stringop-overread]
1709 | if (ath11k_peer_assoc_h_ht_masked(ht_mcs_mask))
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This happens whenever gcc-13 fails to inline one of the functions
that take a fixed-length array argument but gets passed a pointer.
Change these functions to all take a regular pointer argument
instead.

Subject: [PATCH 71/77] wifi: ath11k: driver settings for MBSSID and EMA
Advertise the driver support for multiple BSSID (MBSSID) and
enhanced multi-BSSID advertisements (EMA) by setting extended
capabilities.
Configure mbssid_max_interfaces and ema_max_profile_periodicity
fields in structure wiphy which are used to advertise maximum number
of interfaces and profile periodicity supported by the driver.
Add new WMI fields to configure maximum vdev count supported for
MBSSID and profile periodicity in case of EMA.
Setting WMI_RSRC_CFG_FLAG2_CALC_NEXT_DTIM_COUNT_SET flag
indicates that the firmware should track and update the DTIM counts
for each non-transmitted profile.

Subject: [PATCH 73/77] wifi: ath11k: rename MBSSID fields in wmi_vdev_up_cmd
Rename trans_bssid to tx_vdev_bssid to make it similar to vdev_bssid.
Rename profile_num to nontx_profile_cnt, and profile_idx to
nontx_profile_idx which makes it clear that these store configurations
related to MBSSID non-transmitting profiles.

Subject: [PATCH 75/77] wifi: ath11k: refactor vif parameter configurations
Security parameters for each non-transmitting profile can be
different when MBSSID is enabled and this information is included
in the MBSSID element in the Beacon frame. Current implementation
to set rsnie_present and wpaie_present does not parse this element
hence it applies only to the transmitting interface.
Move the code to a separate function to make additions for
non-transmitting interfaces cleaner.

Subject: [PATCH 76/77] wifi: ath11k: MBSSID beacon support
- Split ath11k_mac_setup_bcn_tmpl() to move the beacon retrieval and
WMI command to a new function, ath11k_mac_setup_bcn_tmpl_legacy().
In the original function add checks to use the transmitting interface
when MBSSID is enabled.
- Set rsnie_present and wpaie_present fields for the non-transmitting
interfaces when MBSSID is enabled.

Subject: [PATCH] wifi: ath11k: Relocate the func
ath11k_mac_bitrate_mask_num_ht_rates() and change hweight16 to hweight8
Relocate the function ath11k_mac_bitrate_mask_num_ht_rates() definition
to call this function from other functions which helps to avoid the
compilation error (function not defined).
ht_mcs[] is 1 byte array and it is enough to use hweight8() instead
of hweight16(). Hence, fixed the same.
Tested on: Compile tested only.

Subject: [PATCH] wifi: ath11k: Send HT fixed rate in WMI peer fixed param
Due to the firmware behavior with HT fixed rate setting,
HT fixed rate MCS with NSS > 1 are treated as NSS = 1
HT rates in the firmware and enables the HT fixed rate of
NSS = 1.
This leads to HT fixed rate is always configured for NSS = 1
even though the user sets NSS = 2 or > 1 HT fixed MCS in the
set bitrate command.
Currently HT fixed MCS is sent via WMI peer assoc command.
Fix this issue, by sending the HT fixed rate MCS in WMI peer
fixed param instead of sending in peer assoc command.

Subject: [PATCH] wifi: ath11k: add support default regdb while searching
board-2.bin for WCN6855
Sometimes board-2.bin does not have the regdb data which matched the
parameters such as vendor, device, subsystem-vendor, subsystem-device
and etc. Add default regdb data with 'bus=%s' into board-2.bin for
WCN6855, then ath11k use 'bus=pci' to search regdb data in board-2.bin
for WCN6855.

From b43310e44edc823a7f02af1e1e2b4e8a9abc7d91 Mon Sep 17 00:00:00 2001
From: Govindaraj Saminathan <quic_gsaminat@quicinc.com>
Date: Fri, 26 May 2023 12:41:07 +0300
Subject: [PATCH 83/84] wifi: ath11k: factory test mode support
Add support to process factory test mode commands (FTM) for calibration.
By default firmware start with NORMAL mode and to process the FTM commands
firmware needs to be restarted in FTM mode using module parameter ftm_mode.
The pre-request is all the radios should be down before starting the test.
When start command ATH11K_TM_CMD_TESTMODE_START is received, ar->state
is set to Test Mode. If the FTM command or event length is greater
than 256 bytes, it will be broken down into multiple segments and
encoded with TLV header if it is segmented commands, else it is sent
to firmware as it is.
On receiving UTF event from firmware, if it is segmented event, the driver
will wait until it receives all the segments and notify the complete
data to user application. In case the segmented sequence are missed or
lost from the firmware, driver will skip the already received partial data.
In case of unsegmented UTF event from firmware, driver notifies the
data to the user application as it comes. Applications handles
the data further.
Command to boot in ftm mode:
insmod ath11k ftm_mode=1
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1

Subject: [PATCH 84/84] wifi: ath11k: Allow ath11k to boot without caldata in
ftm mode
Currently, if ath11k is unable to load the calibration data file it will
always exit. However the calibration data may not be present in factory
test mode, so update the logic to allow the driver to execute in FTM mode
even if downloading the calibration data fails.

Subject: [PATCH] wifi: ath11k: Add HTT stats for PHY reset case
New HTT stats are added with stats type 37 to
provide PHY reset stats and PHY reset counter stats.
PHY reset stats are used to display the current
PHY-related operation information such as band, CCA
threshold, current operating channel etc.,
PHY reset counter stats are used to display the
PHY reset counter values like calibration counts,
temperature based recalibration counts etc.,
Usage:
echo 37 > /sys/kernel/debug/ieee80211/phyX/ath11k/htt_stats_type
cat /sys/kernel/debug/ieee80211/phyx/ath11k/htt_stats

From bd54f3c29077f23dad92ef82a78061b40be30c65 Mon Sep 17 00:00:00 2001
From: Aloka Dixit <quic_alokad@quicinc.com>
Date: Mon, 5 Dec 2022 16:50:37 -0800
Subject: [PATCH] wifi: mac80211: generate EMA beacons in AP mode
Add APIs to generate an array of beacons for an EMA AP (enhanced
multiple BSSID advertisements), each including a single MBSSID element.
EMA profile periodicity equals the count of elements.
- ieee80211_beacon_get_template_ema_list() - Generate and return all
EMA beacon templates. Drivers must call ieee80211_beacon_free_ema_list()
to free the memory. No change in the prototype for the existing API,
ieee80211_beacon_get_template(), which should be used for non-EMA AP.
- ieee80211_beacon_get_template_ema_index() - Generate a beacon which
includes the multiple BSSID element at the given index. Drivers can use
this function in a loop until NULL is returned which indicates end of
available MBSSID elements.
- ieee80211_beacon_free_ema_list() - free the memory allocated for the
list of EMA beacon templates.
Modify existing functions ieee80211_beacon_get_ap(),
ieee80211_get_mbssid_beacon_len() and ieee80211_beacon_add_mbssid()
to accept a new parameter for EMA index.

Subject: [PATCH] leds: Move led_init_default_state_get() to the global header
There are users inside and outside LED framework that have implemented
a local copy of led_init_default_state_get(). In order to deduplicate
that, as the first step move the declaration from LED header to the
global one.

Move qca8k_port_to_phy() to qca8k header as it's useful for future
reference in Switch LEDs module since the same logic is applied to get
the right index of the switch port.
Make it inline as it's simple function that just decrease the port.

Subject: [PATCH 2/9] net: dsa: qca8k: add LEDs basic support
Add LEDs basic support for qca8k Switch Family by adding basic
brightness_set() support.
Since these LEDs refelect port status, the default label is set to
":port". DT binding should describe the color and function of the
LEDs using standard LEDs api.
Each LED always have the device name as prefix. The device name is
composed from the mii bus id and the PHY addr resulting in example
names like:
- qca8k-0.0:00:amber:lan
- qca8k-0.0:00:white:lan
- qca8k-0.0:01:amber:lan
- qca8k-0.0:01:white:lan
These LEDs supports only blocking variant of the brightness_set()
function since they can sleep during access of the switch leds to set
the brightness.
While at it add to the qca8k header file each mode defined by the Switch
Documentation for future use.

Subject: [PATCH 4/9] leds: Provide stubs for when CLASS_LED & NEW_LEDS are
disabled
Provide stubs for devm_led_classdev_register_ext() and
led_init_default_state_get() so that LED drivers embedded within other
drivers such as PHYs and Ethernet switches still build when LEDS_CLASS
or NEW_LEDS are disabled. This also helps with Kconfig dependencies,
which are somewhat hairy for phylib and mdio and only get worse when
adding a dependency on LED_CLASS.

Subject: [PATCH 5/9] net: phy: Add a binding for PHY LEDs
Define common binding parsing for all PHY drivers with LEDs using
phylib. Parse the DT as part of the phy_probe and add LEDs to the
linux LED class infrastructure. For the moment, provide a dummy
brightness function, which will later be replaced with a call into the
PHY driver. This allows testing since the LED core might otherwise
reject an LED whose brightness cannot be set.
Add a dependency on LED_CLASS. It either needs to be built in, or not
enabled, since a modular build can result in linker errors.

Subject: [PATCH 1/5] leds: trigger: netdev: Recheck NETDEV_LED_MODE_LINKUP on
dev rename
Dev can be renamed also while up for supported device. We currently
wrongly clear the NETDEV_LED_MODE_LINKUP flag on NETDEV_CHANGENAME
event.
Fix this by rechecking if the carrier is ok on NETDEV_CHANGENAME and
correctly set the NETDEV_LED_MODE_LINKUP bit.

Subject: [PATCH 2/5] leds: trigger: netdev: Drop NETDEV_LED_MODE_LINKUP from
mode
Putting NETDEV_LED_MODE_LINKUP in the same list of the netdev trigger
modes is wrong as it's used to set the link state of the device and not
to set a blink mode as it's done by NETDEV_LED_LINK, NETDEV_LED_TX and
NETDEV_LED_RX. It's also wrong to put this state in the same bitmap of the
netdev trigger mode and should be external to it.
Drop NETDEV_LED_MODE_LINKUP from mode list and convert to a simple bool
that will be true or false based on the carrier link. No functional
change intended.

Subject: [PATCH 5/5] leds: trigger: netdev: Use mutex instead of spinlocks
Some LEDs may require to sleep while doing some operation like setting
brightness and other cleanup.
For this reason, using a spinlock will cause a sleep under spinlock
warning.
It should be safe to convert this to a sleepable lock since:
- sysfs read/write can sleep
- netdev_trig_work is a work queue and can sleep
- netdev _trig_notify can sleep
The spinlock was used when brightness didn't support sleeping, but this
changed and now it supported with brightness_set_blocking().
Convert to mutex lock to permit sleeping using brightness_set_blocking().

hardware.
Add hw_control_is_supported() to ask the LED driver if the requested

Some specific LED triggers blink the LED based on events from a device
or subsystem.
For example, an LED could be blinked to indicate a network device is
receiving packets, or a disk is reading blocks. To correctly enable and
request the hw control of the LED, the trigger has to check if the
network interface or block device configured via a /sys/class/led file
match the one the LED driver provide for hw control for.
Provide an API call to get the device which the LED blinks for.

+Hardware driven LEDs
+====================
+
+Some LEDs can be programmed to be driven by hardware. This is not
+limited to blink but also to turn off or on autonomously.
+To support this feature, a LED needs to implement various additional
+ops and needs to declare specific support for the supported triggers.
+
+With hw control we refer to the LED driven by hardware.
+
+LED driver must define the following value to support hw control:
+
+ - hw_control_trigger:
+ unique trigger name supported by the LED in hw control
+ mode.
+
+LED driver must implement the following API to support hw control:
+ - hw_control_is_supported:
+ check if the flags passed by the supported trigger can
+ be parsed and activate hw control on the LED.
+
+ Return 0 if the passed flags mask is supported and
+ can be set with hw_control_set().
+
+ If the passed flags mask is not supported -EOPNOTSUPP
+ must be returned, the LED trigger will use software
+ fallback in this case.
+
+ Return a negative error in case of any other error like
+ device not ready or timeouts.
+
+ - hw_control_set:
+ activate hw control. LED driver will use the provided
+ flags passed from the supported trigger, parse them to
+ a set of mode and setup the LED to be driven by hardware
+ following the requested modes.
+
+ Set LED_OFF via the brightness_set to deactivate hw control.
+
+ Return 0 on success, a negative error number on failing to
+ apply flags.
+
+ - hw_control_get:
+ get active modes from a LED already in hw control, parse
+ them and set in flags the current active flags for the
+ supported trigger.
+
+ Return 0 on success, a negative error number on failing
+ parsing the initial mode.
+ Error from this function is NOT FATAL as the device may
+ be in a not supported initial state by the attached LED
+ trigger.
+
+ - hw_control_get_device:
+ return the device associated with the LED driver in
+ hw control. A trigger might use this to match the
+ returned device from this function with a configured
+ device for the trigger as the source for blinking
+ events and correctly enable hw control.
+ (example a netdev trigger configured to blink for a
+ particular dev match the returned dev from get_device
+ to set hw control)
+
+ Returns a pointer to a struct device or NULL if nothing
+ is currently attached.
+
+LED driver can activate additional modes by default to workaround the
+impossibility of supporting each different mode on the supported trigger.
+Examples are hardcoding the blink speed to a set interval, enable special
+feature like bypassing blink if some requirements are not met.
+
+A trigger should first check if the hw control API are supported by the LED
+driver and check if the trigger is supported to verify if hw control is possible,
+use hw_control_is_supported to check if the flags are supported and only at
+the end use hw_control_set to activate hw control.
+
+A trigger can use hw_control_get to check if a LED is already in hw control
+and init their flags.
+
+When the LED is in hw control, no software blink is possible and doing so
+will effectively disable hw control.

Add knob with the new value hw_control in trigger_data struct to
set hw control possible. Useful for future implementation to implement
in set_baseline_state() the required function to set the requested mode
using LEDs hw control ops and in other function to reject set if hw
control is currently active.

Subject: [PATCH 08/13] leds: trigger: netdev: add support for LED hw control
Add support for LED hw control for the netdev trigger.
The trigger on calling set_baseline_state to configure a new mode, will
do various check to verify if hw control can be used for the requested
mode in can_hw_control() function.
It will first check if the LED driver supports hw control for the netdev
trigger, then will use hw_control_is_supported() and finally will call
hw_control_set() to apply the requested mode.
To use such mode, interval MUST be set to the default value and net_dev
MUST be set. If one of these 2 value are not valid, hw control will
never be used and normal software fallback is used.
The default interval value is moved to a define to make sure they are
always synced.

Subject: [PATCH 13/13] net: dsa: qca8k: add op to get ports netdev
In order that the LED trigger can blink the switch MAC ports LED, it
needs to know the netdev associated to the port. Add the callback to
return the struct device of the netdev.
Add an helper function qca8k_phy_to_port() to convert the phy back to
dsa_port index, as we reference LED port based on the internal PHY
index and needs to be converted back.

Subject: [PATCH] net: page_pool: use in_softirq() instead
We use BH context only for synchronization, so we don't care if it's
actually serving softirq or not.
As a side node, in case of threaded NAPI, in_serving_softirq() will
return false because it's in process context with BH off, making
page_pool_recycle_in_cache() unreachable.

Subject: [PATCH] leds: Move led_init_default_state_get() to the global header
There are users inside and outside LED framework that have implemented
a local copy of led_init_default_state_get(). In order to deduplicate
that, as the first step move the declaration from LED header to the
global one.

Subject: [PATCH 1/9] net: dsa: qca8k: move qca8k_port_to_phy() to header
Move qca8k_port_to_phy() to qca8k header as it's useful for future
reference in Switch LEDs module since the same logic is applied to get
the right index of the switch port.
Make it inline as it's simple function that just decrease the port.

Subject: [PATCH 2/9] net: dsa: qca8k: add LEDs basic support
Add LEDs basic support for qca8k Switch Family by adding basic
brightness_set() support.
Since these LEDs refelect port status, the default label is set to
":port". DT binding should describe the color and function of the
LEDs using standard LEDs api.
Each LED always have the device name as prefix. The device name is
composed from the mii bus id and the PHY addr resulting in example
names like:
- qca8k-0.0:00:amber:lan
- qca8k-0.0:00:white:lan
- qca8k-0.0:01:amber:lan
- qca8k-0.0:01:white:lan
These LEDs supports only blocking variant of the brightness_set()
function since they can sleep during access of the switch leds to set
the brightness.
While at it add to the qca8k header file each mode defined by the Switch
Documentation for future use.

Add LEDs blink_set() support to qca8k Switch Family.
These LEDs support hw accellerated blinking at a fixed rate
of 4Hz.
Reject any other value since not supported by the LEDs switch.

Subject: [PATCH 4/9] leds: Provide stubs for when CLASS_LED & NEW_LEDS are
disabled
Provide stubs for devm_led_classdev_register_ext() and
led_init_default_state_get() so that LED drivers embedded within other
drivers such as PHYs and Ethernet switches still build when LEDS_CLASS
or NEW_LEDS are disabled. This also helps with Kconfig dependencies,
which are somewhat hairy for phylib and mdio and only get worse when
adding a dependency on LED_CLASS.

Subject: [PATCH 5/9] net: phy: Add a binding for PHY LEDs
Define common binding parsing for all PHY drivers with LEDs using
phylib. Parse the DT as part of the phy_probe and add LEDs to the
linux LED class infrastructure. For the moment, provide a dummy
brightness function, which will later be replaced with a call into the
PHY driver. This allows testing since the LED core might otherwise
reject an LED whose brightness cannot be set.
Add a dependency on LED_CLASS. It either needs to be built in, or not
enabled, since a modular build can result in linker errors.

Subject: [PATCH 9/9] net: phy: marvell: Implement led_blink_set()
The Marvell PHY can blink the LEDs, simple on/off. All LEDs blink at
the same rate, and the reset default is 84ms per blink, which is
around 12Hz.

Subject: [PATCH 1/5] leds: trigger: netdev: Recheck NETDEV_LED_MODE_LINKUP on
dev rename
Dev can be renamed also while up for supported device. We currently
wrongly clear the NETDEV_LED_MODE_LINKUP flag on NETDEV_CHANGENAME
event.
Fix this by rechecking if the carrier is ok on NETDEV_CHANGENAME and
correctly set the NETDEV_LED_MODE_LINKUP bit.

Subject: [PATCH 2/5] leds: trigger: netdev: Drop NETDEV_LED_MODE_LINKUP from
mode
Putting NETDEV_LED_MODE_LINKUP in the same list of the netdev trigger
modes is wrong as it's used to set the link state of the device and not
to set a blink mode as it's done by NETDEV_LED_LINK, NETDEV_LED_TX and
NETDEV_LED_RX. It's also wrong to put this state in the same bitmap of the
netdev trigger mode and should be external to it.
Drop NETDEV_LED_MODE_LINKUP from mode list and convert to a simple bool
that will be true or false based on the carrier link. No functional
change intended.

Subject: [PATCH 5/5] leds: trigger: netdev: Use mutex instead of spinlocks
Some LEDs may require to sleep while doing some operation like setting
brightness and other cleanup.
For this reason, using a spinlock will cause a sleep under spinlock
warning.
It should be safe to convert this to a sleepable lock since:
- sysfs read/write can sleep
- netdev_trig_work is a work queue and can sleep
- netdev _trig_notify can sleep
The spinlock was used when brightness didn't support sleeping, but this
changed and now it supported with brightness_set_blocking().
Convert to mutex lock to permit sleeping using brightness_set_blocking().

provided modes.
Add APIs for LEDs hw control. These functions will be used to activate
hardware control where a LED will use the provided flags, from an
unique defined supported trigger, to setup the LED to be driven by
hardware.
Add hw_control_is_supported() to ask the LED driver if the requested
mode by the trigger are supported and the LED can be setup to follow
the requested modes.
Deactivate hardware blink control by setting brightness to LED_OFF via
the brightness_set() callback.

Some specific LED triggers blink the LED based on events from a device
or subsystem.
For example, an LED could be blinked to indicate a network device is
receiving packets, or a disk is reading blocks. To correctly enable and
request the hw control of the LED, the trigger has to check if the
network interface or block device configured via a /sys/class/led file
match the one the LED driver provide for hw control for.
Provide an API call to get the device which the LED blinks for.

+Hardware driven LEDs
+====================
+
+Some LEDs can be programmed to be driven by hardware. This is not
+limited to blink but also to turn off or on autonomously.
+To support this feature, a LED needs to implement various additional
+ops and needs to declare specific support for the supported triggers.
+
+With hw control we refer to the LED driven by hardware.
+
+LED driver must define the following value to support hw control:
+
+ - hw_control_trigger:
+ unique trigger name supported by the LED in hw control
+ mode.
+
+LED driver must implement the following API to support hw control:
+ - hw_control_is_supported:
+ check if the flags passed by the supported trigger can
+ be parsed and activate hw control on the LED.
+
+ Return 0 if the passed flags mask is supported and
+ can be set with hw_control_set().
+
+ If the passed flags mask is not supported -EOPNOTSUPP
+ must be returned, the LED trigger will use software
+ fallback in this case.
+
+ Return a negative error in case of any other error like
+ device not ready or timeouts.
+
+ - hw_control_set:
+ activate hw control. LED driver will use the provided
+ flags passed from the supported trigger, parse them to
+ a set of mode and setup the LED to be driven by hardware
+ following the requested modes.
+
+ Set LED_OFF via the brightness_set to deactivate hw control.
+
+ Return 0 on success, a negative error number on failing to
+ apply flags.
+
+ - hw_control_get:
+ get active modes from a LED already in hw control, parse
+ them and set in flags the current active flags for the
+ supported trigger.
+
+ Return 0 on success, a negative error number on failing
+ parsing the initial mode.
+ Error from this function is NOT FATAL as the device may
+ be in a not supported initial state by the attached LED
+ trigger.
+
+ - hw_control_get_device:
+ return the device associated with the LED driver in
+ hw control. A trigger might use this to match the
+ returned device from this function with a configured
+ device for the trigger as the source for blinking
+ events and correctly enable hw control.
+ (example a netdev trigger configured to blink for a
+ particular dev match the returned dev from get_device
+ to set hw control)
+
+ Returns a pointer to a struct device or NULL if nothing
+ is currently attached.
+
+LED driver can activate additional modes by default to workaround the
+impossibility of supporting each different mode on the supported trigger.
+Examples are hardcoding the blink speed to a set interval, enable special
+feature like bypassing blink if some requirements are not met.
+
+A trigger should first check if the hw control API are supported by the LED
+driver and check if the trigger is supported to verify if hw control is possible,
+use hw_control_is_supported to check if the flags are supported and only at
+the end use hw_control_set to activate hw control.
+
+A trigger can use hw_control_get to check if a LED is already in hw control
+and init their flags.
+
+When the LED is in hw control, no software blink is possible and doing so
+will effectively disable hw control.

Add knob with the new value hw_control in trigger_data struct to
set hw control possible. Useful for future implementation to implement
in set_baseline_state() the required function to set the requested mode
using LEDs hw control ops and in other function to reject set if hw
control is currently active.

Subject: [PATCH 08/13] leds: trigger: netdev: add support for LED hw control
Add support for LED hw control for the netdev trigger.
The trigger on calling set_baseline_state to configure a new mode, will
do various check to verify if hw control can be used for the requested
mode in can_hw_control() function.
It will first check if the LED driver supports hw control for the netdev
trigger, then will use hw_control_is_supported() and finally will call
hw_control_set() to apply the requested mode.
To use such mode, interval MUST be set to the default value and net_dev
MUST be set. If one of these 2 value are not valid, hw control will
never be used and normal software fallback is used.
The default interval value is moved to a define to make sure they are
always synced.

Subject: [PATCH 09/13] leds: trigger: netdev: validate configured netdev
The netdev which the LED should blink for is configurable in
/sys/class/led/foo/device_name. Ensure when offloading that the
configured netdev is the same as the netdev the LED is associated
with. If it is not, only perform software blinking.

Subject: [PATCH 10/13] leds: trigger: netdev: init mode if hw control already
active
On netdev trigger activation, hw control may be already active by
default. If this is the case and a device is actually provided by
hw_control_get_device(), init the already active mode and set the
bool to hw_control bool to true to reflect the already set mode in the
trigger_data.

Subject: [PATCH 12/13] net: dsa: qca8k: implement hw_control ops
Implement hw_control ops to drive Switch LEDs based on hardware events.
Netdev trigger is the declared supported trigger for hw control
operation and supports the following mode:
- tx
- rx
When hw_control_set is called, LEDs are set to follow the requested
mode.
Each LEDs will blink at 4Hz by default.

Subject: [PATCH 13/13] net: dsa: qca8k: add op to get ports netdev
In order that the LED trigger can blink the switch MAC ports LED, it
needs to know the netdev associated to the port. Add the callback to
return the struct device of the netdev.
Add an helper function qca8k_phy_to_port() to convert the phy back to
dsa_port index, as we reference LED port based on the internal PHY
index and needs to be converted back.
