From 35622dc26eeb1c9046df659be43b3a9316b0bf65 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Sun, 26 Aug 2012 08:54:41 +0800 Subject: [PATCH] wireless: use is_broadcast_ether_addr() instead of memcmp() Using is_broadcast_ether_addr() instead of directly use memcmp() to determine if the ethernet address is broadcast address. spatch with a semantic match is used to found this problem.
