Merge branch 'addr_compare'

Ding Tianhong says:

====================
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.
