We're only talking about IPv6, right?  IPv4 ARP packets have no
alignment requirements and thus no need for padding as far as I know.

For IPv6, I have already written a patch for net/ipv6/ndisc.c that
adds the padding before the link address.  It makes sense to make this
more generic because RFC 3381 already requires padding before the
address.  Unless we decide to modify the IPoIB draft it's no problem
to send this patch upstream.
