From 69687a0b9934942e61bf8148c242adea87183a5b Mon Sep 17 00:00:00 2001 From: Luis Carlos Cobo Date: Mon, 5 May 2008 12:29:42 -0700 Subject: mac80211: fix access to null skb Without this patch, if xmit_skb is null but net_ratelimit() returns 0 we would go to the else branch and access the null xmit_skb.

The addresses passed to compare_ether_addr should be two bytes aligned. It may function properly in x86 platform. However may not work properly on IA-64 or ARM processor. This also fixes a typo in mlme.c where the sk_buff struct name is incorect. Though sizeof() works for any incorrect structure pointer name as its just a pointer length that we want, lets just fix it.
