From 8fdd01530cda849ba531e7e9d8674fbc81ab5782 Mon Sep 17 00:00:00 2001 From: Antonio Quartulli Date: Wed, 22 Jan 2014 00:42:11 +0100 Subject: [PATCH] batman-adv: prefer ether_addr_copy to memcpy On some architectures ether_addr_copy() is slightly faster than memcpy() therefore use the former when possible.
