mac80211: notify the driver upon BAR Rx
When we receive a BAR, this typically means that our peer doesn't hear our Block-Acks or that we can't hear its frames. Either way, it is a good indication that the link is in a bad condition. This is why it can serve as a probe to the driver. Use the event_callback callback for this. Since more events with the same data will be added in the feature, the structure that describes the data attached to the event is called in a generic name: ieee80211_ba_event. This also means that from now on, the event_callback can't sleep. Signed-off-by: NEmmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: NJohannes Berg <johannes.berg@intel.com>
