From 94ba92713f8329c96e0a8e2880b3c1a785d1c95c Mon Sep 17 00:00:00 2001 From: Ilan Peer Date: Mon, 19 Feb 2018 14:48:41 +0200 Subject: mac80211: Call mgd_prep_tx before transmitting deauthentication In multi channel scenarios, when disassociating from the AP before a beacon was heard from the AP, it is not guaranteed that the virtual interface is granted air time for the transmission of the deauthentication frame. This in turn can lead to various issues as the AP might never get the deauthentication frame. To mitigate such possible issues, add a HW flag indicating that the driver requires mac80211 to call the mgd_prep_tx() driver callback to make sure that the virtual interface is granted immediate airtime to be able to transmit the frame, in case that no beacon was heard from the AP.
