Hmm, this means we have to patch all filrewalls(pf/ipfw/ipf), carp(4)
and possibily netgraph(4) too. I'm afraid this is not right direction
to go. Alignment fixup would be best served in ether_input or in driver
layer which seems to be more appropriate place. Maybe this is the
reason why OpenBSD have such a complex alignment code in em driver.
