Subject: [B.A.T.M.A.N.] [PATCH -next] batadv: Slight optimization of batadv_compare_eth
Date: Fri, 06 Dec 2013 14:39:46 -0800 [thread overview]
Message-ID: <1386369586.31845.42.camel@joe-AO722> (raw)
In-Reply-To: <1386368461.31845.38.camel@joe-AO722>
Use the newly added generic routine ether_addr_equal_unaligned
to test if possibly unaligned to u16 Ethernet addresses are equal.
This slightly improves comparison time for systems with
CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS.
