Subject: [PATCH] wifi: ath11k: stop tx queues immediately upon firmware exit
|
|
|
|
Currently, recovery flag is set immediately upon firmware
|
|
exit but tx queues are stopped once firmware arrives back
|
|
and is ready which is during ath11k_core_restart. Once
|
|
ieee80211 hw restart is completed, tx queues are resumed.
|
|
If during the time delta between firmware exit and firmware
|
|
ready, mac80211 send packets, currently ath11k will drop it
|
|
since recovery flag will be set. But warning prints will
|
|
come -
|
|
"ath11k c000000.wifi: failed to transmit frame -108"
|
|
|
|
If more tx packets are there, this could lead to flooding
|
|
of above print.
|
|
|
|
However, actually tx queues should be stopped immediately
|
|
when firmware leaves. This will prevent packets to get
|
|
dropped when firmware is recovering.
|
|
|
|
Add fix to stop tx queues immediately after firmware exit.
|
|
