From 4644ae89033872a62b4fea6ca96b958e115efdc0 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 28 Mar 2012 11:04:28 +0200 Subject: mac80211: lazily stop queues in add_pending When adding pending SKBs there's no need to stop all queues, we only need to stop those that we're adding frames to. Implement that by lazily stopping a queue as we add an SKB. Signed-off-by: Johannes Berg Signed-off-by: John W.
