From: Joe Perches Date: Wed, 9 May 2012 17:04:04 +0000 (+0000) Subject: net, drivers/net: Convert compare_ether_addr_64bits to ether_addr_equal_64bits X-Git-Tag: v3.5-rc1~109^2~110 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a6700db17980972199e61c06be535a79e1b0b4e6;p=platform%2Fupstream%2Fkernel-adaptation-pc.git net, drivers/net: Convert compare_ether_addr_64bits to ether_addr_equal_64bits Use the new bool function ether_addr_equal_64bits to add some clarity and reduce the likelihood for misuse of compare_ether_addr_64bits for sorting.
