From 0eeb2b674f05ccb5162a1d68c0b8ae81e25fd972 Mon Sep 17 00:00:00 2001 From: Sara Sharon Date: Wed, 5 Sep 2018 08:06:09 +0300 Subject: mac80211: add an option for station management TXQ We have a TXQ abstraction for non-data packets that need powersave buffering. Since the AP cannot sleep, in case of station we can use this TXQ for all management frames, regardless if they are bufferable. Add HW flag to allow that.
