[PATCH 1/2] mac80211: Update the driver with beacon info constantly

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Doru Gucea <gucea.doru@xxxxxxxxx>

Once the mac80211 layer receives a beacon, it should send a notification
to the driver. This will allow finer timining control in case of drivers
that need a correct estimation for the arrival time of a beacon.
