[PATCH 9/11] ipw2x00: use ether_addr_equal_64bits

From: Julia Lawall
Date: Mon Dec 30 2013 - 12:22:22 EST

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 structure involved is
libipw_network defined in drivers/net/wireless/ipw2x00/libipw.h

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

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

The semantic patch used is rather long and can be found in message 0 of
this patch series.
