From ada0f8633c5b8dad640e1a2bcb95499ec187ac17 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Sat, 15 Feb 2014 16:02:17 -0800 Subject: bonding: Convert memcpy(foo, bar, ETH_ALEN) to ether_addr_copy(foo, bar) ether_addr_copy is smaller and faster for some architectures. This relies on a stack frame being at least __aligned(2) for one use of an Ethernet address on the stack. Signed-off-by: Joe Perches Signed-off-by: David S.
