Subject: [PATCH] mac80211: remove STA txq pending airtime underflow
|
|
warning
|
|
|
|
This warning can trigger if there is a mismatch between frames that were
|
|
sent with the sta pointer set vs tx status frames reported for the sta address.
|
|
|
|
This can happen due to race conditions on re-creating stations, or even
|
|
in the case of .sta_add/remove being used instead of .sta_state, which can cause
|
|
frames to be sent to a station that has not been uploaded yet.
|
|
|
|
If there is an actual underflow issue, it should show up in the device airtime
|
|
warning below, so it is better to remove this one.
