It's convenient to have ethernet mac addresses use ETH_ALEN to be able to grep for them a bit easier and also to ensure that the addresses are __aligned(2). Add #include <linux/if_ether.h> as necessary. Signed-off-by: Joe Perches <joe@perches.com> Acked-by: Mauro Carvalho Chehab <m.chehab@samsung.com> Signed-off-by: David S. Miller <davem@davemloft.net>
