Subject: [PATCH] wifi: rtw88: usb: Upload the firmware in bigger chunks
RTL8811AU stops responding during the firmware download on some systems:
[ 809.256440] rtw_8821au 5-2.1:1.0: Firmware version 42.4.0, H2C version 0
[ 812.759142] rtw_8821au 5-2.1:1.0 wlp48s0f4u2u1: renamed from wlan0
[ 837.315388] rtw_8821au 1-4:1.0: write register 0x1ef4 failed with -110
[ 867.524259] rtw_8821au 1-4:1.0: write register 0x1ef8 failed with -110
[ 868.930976] rtw_8821au 5-2.1:1.0 wlp48s0f4u2u1: entered promiscuous mode
[ 897.730952] rtw_8821au 1-4:1.0: write register 0x1efc failed with -110
Maybe it takes too long when writing the firmware 4 bytes at a time.
Write 196 bytes at a time for RTL8821AU, RTL8811AU, and RTL8812AU,
and 254 bytes at a time for RTL8723DU. These are the sizes used in
their official drivers. Tested with all these chips.
