From 64b6f46f1141ad938e354f37af62e28da972e8eb Mon Sep 17 00:00:00 2001 From: Sujith Manoharan Date: Mon, 15 Jul 2013 11:03:57 +0530 Subject: [PATCH] ath9k_hw: Fix multicast search for AR9002 family The multicast search bit is disabled for the AR9003 family, but this is required for AR9002 too. Fix this in the INI override routine. Signed-off-by: Sujith Manoharan Signed-off-by: John W.
