slight optimization of addr compare for some modules

Joe Perches add ether_addr_equal_unaligned to test if possibly unaligned to u16 Ethernet addresses are equal.

If CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS is set, this uses the slightly faster generic routine ether_addr_equal, otherwise this uses memcmp.

So I use the recently added and possibly more efficient ether_addr_equal_unaligned to instead of memcmp for slight optimization.

v2: Because a lot of places are already using 16b aligned MAC
address for both operands, so use the ether_addr_equal to instead of ether_addr_equal_unaligned.Thanks for Joe, Alex and Antonio's opinions.
Also remove the patch for bridge.

v3: According Joe's suggestion, the patch
(net: slight optimization of addr compare for some modules) should be broken into several patches, and it will be good to review for maintainers. So I will send rest of the patches for first step, and next step, I will seperate the netdev patch and send them by another patchset for net-next.
also fix some changelog.

v3.5 Change some style for patch 8 and patch 13. Thanks for
Sergei's suggestion.

v3.6 Change some style for patch 13 and add

Best Regards
Ding
