From 445ea4e83ec50668cc9ad7e5cf96d242f19165e8 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 13 Feb 2013 12:25:28 +0100 Subject: mac80211: stop queues temporarily for flushing Sometimes queues are flushed in the middle of operation, which can lead to driver issues. Stop queues temporarily, while flushing, to avoid transmitting new packets while they are being flushed.
