erm mbufs will be aligned on a 4 byte boundry. There is no obvious way to
detect at compile time if it is an mbuf or not so the best thing would be to
look out for 128 bytes copies and use a dedicated routine.

Yep but I have not seen it yet. I have one assembly version but there appears
to be a problem with some packets that causes bad checksums to be generated.
