From 9da27232060411e98c27a8407610c794acb08c8b Mon Sep 17 00:00:00 2001 From: Sujith Manoharan Date: Thu, 16 Feb 2012 11:53:00 +0530 Subject: ath9k: Fix descriptor length for AR9462 Change the descriptor length to 24 and explicitly set the control field 23 to zero. Not doing so would result in dropping of frames. Signed-off-by: Sujith Manoharan Signed-off-by: John W.
