From 84c9e164468bd707e52b440e1c34bc3c85299332 Mon Sep 17 00:00:00 2001 From: Sujith Manoharan Date: Wed, 13 Apr 2011 11:26:11 +0530 Subject: ath9k_htc: Drain packets on station removal When a station entry is removed, there could still be pending packets destined for that station in the HIF layer. Sending these to the target is not necessary, so drain them in the driver itself. Signed-off-by: Sujith Manoharan Signed-off-by: John W.
