From c0321505df2eedfb468512d629cd198b1abc2d03 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 29 Mar 2017 14:15:24 +0200 Subject: [PATCH] mac80211: unconditionally start new netdev queues with iTXQ support commit 7d65f82954dadbbe7b6e1aec7e07ad17bc6d958b upstream. When internal mac80211 TXQs aren't supported, netdev queues must always started out started even when driver queues are stopped while the interface is added. This is necessary because with the internal TXQ support netdev queues are never stopped and packet scheduling/dropping is done in mac80211.
