Subject: net:drivers/net: Miscellaneous conversions to ETH_ALEN
X-Git-Tag: accepted/tizen/common/20141203.182822~1141^2~238
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d458cdf712e0c671e8e819abb16ecd6e44f9daec;p=platform%2Fkernel%2Flinux-arm64.git

net:drivers/net: Miscellaneous conversions to ETH_ALEN

Convert the memset/memcpy uses of 6 to ETH_ALEN
where appropriate.

Also convert some struct definitions and u8 array
declarations of [6] to ETH_ALEN.
