From: Johannes Berg Date: Mon, 7 May 2012 15:45:29 +0000 (+0200) Subject: mac80211: fix single queue drivers X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=a9d3c05cca51d80ef2b9eddabf794c9458e36c2c;p=deliverable%2Flinux.git mac80211: fix single queue drivers My queue management rework broke drivers that don't have multiple AC queues and register a single queue only, causing a warning: WARNING: at net/mac80211/iface.c:162 ieee80211_check_queues This was due to filling the queues wrongly and then noticing the error when checking later.
