-Subject: [PATCH] wifi: mac80211: introduce
- ieee80211_refresh_tx_agg_session_timer()
-
-This allows low level drivers to refresh the tx agg session timer, based on
-querying stats from the firmware usually. Especially for some mt76 devices
-support .net_fill_forward_path would bypass mac80211, which leads to tx BA
-session timeout for certain clients.
