From ac06713d55d450cbc9ef871b1b238409238f0fe0 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Tue, 1 Sep 2009 05:46:05 +0000 Subject: [PATCH] macvlan: Use compare_ether_addr_64bits() To speedup ether addresses compares, we can use compare_ether_addr_64bits() (all operands are guaranteed to be at least 8 bytes long) Signed-off-by: Eric Dumazet Signed-off-by: David S.
