nf_nat_helper.c:mangle_content() could make use of this, but it
would need memmove. Something to do this with non-linear packets
would be even cooler :)

Damn, that was so fast man! For the qeth case that motivated me to try
the leftover it was like: memcpy is the fastest way, memmove would be
more costly but more general, when in doubt I just droppped the users
without removing the infrastructure, nah, lets leave this for another
day, for now I'll just drop the non-used -new infrastrucure and
resubmit.

Yes, as long as it doesn't help with anything else it doesn't seem
too useful. It did motivate me to try the non-linear skb mangling
though :)
