The removed patches were applied upstream. Remove the 300-mac80211-optimize-skb-resizing.patch. This patch was not applied upstream, but it conflicts with upstream changes and needs bigger changes. It was applied with Felix to remove this patch for now. It should be reworked and then send upstream later. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>

Subject: [PATCH] mac80211: do not drop tx nulldata packets on encrypted links
|
|
|
|
ieee80211_tx_h_select_key drops any non-mgmt packets without a key when
|
|
encryption is used. This is wrong for nulldata packets that can't be
|
|
encrypted and are sent out for probing clients and indicating 4-address
|
|
mode.
