From 9d64a3cfaf3edb548b68ef4eedbadbb875eaa10e Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Thu, 14 May 2009 21:28:47 +0300 Subject: [PATCH] ath9k: Clean up RX processing a bit This makes use of the local fc variable in bit more places and uses a common helper macro. The part of RX process that delivers skb's to mac80211 is moved to a separate function in preparation for future changes that will need to do this from two places. The modifications here should not result in any functional changes. Signed-off-by: Jouni Malinen Signed-off-by: John W.
