NSS patches should always get applied last as to avoid fuzzing issues with upstream patches. Also cleanup patches that introduced spaces as indents vs. tabs Signed-off-by: Sean Khan <datapronix@protonmail.com> ath11k_nss: drop upstreamed patch A variation of this patch 'wifi: mac80211: Use flexible array in struct ieee80211_tim_ie' was upstreamed in commit 'e6e4d90b69027d74ba7e9a0a586b95a5714e10c0'.

Subject: [PATCH] ath11k : flush management frames to firmware before waiting
|
|
for tx completion
|
|
|
|
warning print "ath11k c000000.wifi: failed to flush mgmt transmit queue 0"
|
|
is observed during interface down.
|
|
|
|
The management packets are queued in a skb_queue and the skb_queue
|
|
is dequeued in the work ar->wmi_mgmt_tx_work.
|
|
|
|
In ath11k_mac_flush_tx_complete, before waiting for the tx completion of
|
|
all the management frames, we are not ensuring that queued
|
|
management frames are flushed to the firmware.
|
|
|
|
This causes ar->num_pending_mgmt_tx to be positive and it leads to the
|
|
warning print.
|
|
|
|
Fix this by flushing all the management frames to firmware before waiting
|
|
for the tx completion.
