[PATCH 1/11] rt2x00: use ether_addr_equal_64bits

[Julia Lawall]

From: Julia Lawall <Julia.Lawall@xxxxxxx>

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_bar defined in include/linux/ieee80211.h and
rt2x00_bar_list_entry defined in drivers/net/wireless/rt2x00/rt2x00.h.

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

Signed-off-by: Julia Lawall <Julia.Lawall@xxxxxxx>
