From 1c87bbad439d818f94f2e8bff98f73d6fb568dfc Mon Sep 17 00:00:00 2001 From: David Spinadel Date: Thu, 27 Feb 2014 16:41:52 +0200 Subject: iwlwifi: mvm: support extended beacon notification Use extended beacon notification when supported by FW. Set last beacon system time to AP or GO interface. System time of last beacon can be used to avoid TBTT overlapping between two interfaces, CSA and other uses.
