[PATCH 13/21] mac8011: slight optimization of addr compare

From: Ding Tianhong <hidden>
Date: 2013-12-23 05:11:41
Also in: linux-wireless, lkml
Subsystem: mac80211, the rest · Maintainers: Johannes Berg, Linus Torvalds

Use the recently added and possibly more efficient
ether_addr_equal_unaligned to instead of memcmp.
