From 7b1fff996a5408261ca458f82369d1f5b7aad2d4 Mon Sep 17 00:00:00 2001 From: Jussi Kivilinna Date: Fri, 28 Aug 2009 12:59:15 +0300 Subject: [PATCH] rndis_wlan: use is_zero_ether_addr() and is_broadcast_ether_addr() Use is_zero_ether_addr() and is_broadcast_ether_addr() instead of memcmp against ffff_bssid/zero_bssid.
