Subject: [PATCH 3/7] atm: Use ether_addr_copy
Date: Mon, 20 Jan 2014 09:52:16 -0800	[thread overview]
Message-ID: <891b9869ad352a40f4e8f6dea28cf2da0ce6fde7.1390239869.git.joe@perches.com> (raw)
In-Reply-To: <cover.1390239869.git.joe@perches.com>

Use ether_addr_copy instead of memcpy(a, b, ETH_ALEN) to
save some cycles on arm and powerpc.
