Subject: [PATCH] mac80211: fix regression in sta connection monitor
|
|
|
|
When a frame was acked and probe frames were sent, the connection monitoring
|
|
needs to be reset, otherwise it will keep probing until the connection is
|
|
considered dead, even though frames have been acked in the mean time.
|
|
|

Fixes: 9abf4e49830d ("mac80211: optimize station connection monitor")
