From 36ddf203d7aae3fc77caf0e6a53382350b0578d3 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Mon, 30 Dec 2013 19:15:04 +0100 Subject: [PATCH] ath9k: use ether_addr_equal_64bits Ether_addr_equal_64bits is more efficient than ether_addr_equal, and can be used when each argument is an array within a structure that contains at least two bytes of data beyond the array. The structures involved are: ieee80211_hdr defined in include/linux/ieee80211.h ath_common defined in drivers/net/wireless/ath/ath.h This was done using Coccinelle (http://coccinelle.lip6.fr/).
