mac80211: use offchannel queue only when supported
Commit 3a25a8c ("mac80211: add improved HW queue control") added support for offchannel queue mapping. However, this mapping is only valid when the driver supports IEEE80211_HW_QUEUE_CONTROL. Check whether the driver supports IEEE80211_HW_QUEUE_CONTROL before setting the hw_queue to the mapped offchannel queue. (This patch doesn't have any actual effect, because hw_queue is overridden in ieee80211_tx() anyway, so this is merely some cleanup) Signed-off-by: Eliad Peller <eliad@wizery.com> Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
