Of course you are correct.  The 6 octet length of the ethernet address
confused me, sorry.

That's true.  It seems there is some precedent for putting the padding
at both ends: IPv6-over-ARCnet (RFC 2497) puts the (one octet!?) 
ARCnet address at the beginning of the option followed by 5 octects of
padding, while IPv6-over-Fibre Channel (RFC 3381) puts two octets of
padding at the beginning followed by 12 octets of address.

I will generate a patch for the Linux kernel to pad appropriately and
forward it to the networking maintainers.

Does anyone know what Solaris's IPoIB implementation does?

Thanks,
