Subject: batadv: Slight optimization of batadv_compare_eth
X-Git-Tag: v4.14-rc1~8188^2~555
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d9cd4fe5ef4373e0f5b2e752b1859bee33bc5644;p=platform%2Fkernel%2Flinux-rpi.git

batadv: Slight optimization of batadv_compare_eth

Use the newly added generic routine ether_addr_equal_unaligned
to test if possibly unaligned to u16 Ethernet addresses are equal.

This slightly improves comparison time for systems with
CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS.
