WHOOOO HAHAHAHAHAHAH, I FIGURED IT OUT.

We weren't copying over the mbuf flags.  These flags included the HARDWARE
CHECKSUM flags.  Hence, after being reassembled, our mbuf chain was being
sent out unchecksummed, which upset the machines on the other end.

Anyway, now that it appears to be working, I'm going to start working on
the m_defragment function.  After that's good, then I'll clean up xl_encap
to use it.
