Subject: [PATCH 1/2] mac80211: Update the driver with beacon info constantly
Date: Wed, 15 Feb 2017 21:01:18 +0200	[thread overview]
Message-ID: <1487185278-8643-1-git-send-email-gucea.doru@gmail.com> (raw)

From: Doru Gucea <gucea.doru@gmail.com>

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.
