Subject: bridge: Use ether_addr_copy and ETH_ALEN
X-Git-Tag: firefly_0821_release~176^2~4167^2~275
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=e5a727f6632654098fa4e87d8551a5873e8f658a;p=firefly-linux-kernel-4.4.55.git

bridge: Use ether_addr_copy and ETH_ALEN

Convert the more obvious uses of memcpy to ether_addr_copy.

There are still uses of memcpy that could be converted but
these addresses are __aligned(2).

Convert a couple uses of 6 in gr_private.h to ETH_ALEN.
