Now this is definitely broken because it fiddles with TCP packets
in the middle, but still it should *work* in as much as making the
packet go out.  Well except that you need to fix up the checksum
so that it only contains the pseudo-header on output.  That's
probably what you need to address if we failed in avoiding LRO
on forwarded traffic.

Cheers,
