From e2f9ecfcc64c9a7bcb253b57c8bc2e5c87791caa Mon Sep 17 00:00:00 2001 From: Ivan Vecera <ivecera@redhat.com> Date: Thu, 11 Jun 2015 15:52:13 +0200 Subject: bna: use ether_addr_copy instead of memcpy Parameters of all ether_addr_copy instances were checked for proper alignment. Alignment of bnad_bcast_addr is forced to 2 as the implicit alignment is 1. I have also renamed address parameter of bnad_set_mac_address() to addr. The name mac_addr was a little bit confusing as the real parameter is struct sockaddr *. v2: added __aligned directive to bnad_bcast_addr, renamed parameter of bnad_set_mac_address() (thx joe@perches.com) Signed-off-by: Ivan Vecera <ivecera@redhat.com> Signed-off-by: David S.
