This is a slow-path, I don't think that's really worth it. It kinda
makes sense, but relies on the struct mac_address allocation for
alignment and the fact that there are no other members in that struct,
so it seems to me that this ought to also add some alignment attributes?

Yes, I had to say that it is really a slight optimization.And I am sure the address in the struct
is alignment, otherwise I have to use the ether_addr_equal_unaligned().
