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.
