LinuxKPI: add ether_addr_equal_unaligned()

Browse Source 
Replace the implementation for ether_addr_equal() with
ether_addr_equal_unaligned() and add a define for ether_addr_equal()
pointing to the now ether_addr_equal_unaligned() implementation.
This way ether_addr_equal_unaligned() cannot be broken by accident [1].
