Subject: [PATCH] mac80211: ignore tx status for PS stations in
|
||
|
|
ieee80211_tx_status_ext
|
||
|
|
|
||
|
|
Make it behave like regular ieee80211_tx_status calls, except for the lack of
|
||
|
|
filtered frame processing.
|
||
|
|
This fixes spurious low-ack triggered disconnections with powersave clients
|
||
|
|
connected to an AP.
|
||
|
|

||
|
