[PATCH 5/11] mwl8k: use ether_addr_equal_64bits

Julia Lawall

From: Julia Lawall <Julia.Lawall@lip6.fr>

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 and
mwl8k_priv defined in drivers/net/wireless/mwl8k.c

This was done using Coccinelle (http://coccinelle.lip6.fr/).

Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr>
