From 7db062ac4bafac040afb28faf355fc2acb426413 Mon Sep 17 00:00:00 2001 From: Rajkumar Manoharan Date: Wed, 14 Sep 2011 14:20:30 +0530 Subject: [PATCH] ath9k_hw: Do full chip reset on 11A channels for AR9003 AR9003 seems to have issues sometimes with fast channel change in 5GHz and this case is handled specifically for AR9280 by doing a full reset. Let's do a full reset for 5GHz channles of AR9380 & for all channels of AR9280 pci chips. Signed-off-by: Rajkumar Manoharan Signed-off-by: John W.
