    LinuxKPI: add ether_addr_equal_unaligned()
    
    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].
