[dsdp-tm-dev] tcf protocol

[Ed Swarthout <ed@xxxxxxxxxxx>]

I'm working on some of the low-level protocol debug support for TCF.

I captured some packets with a simple scapy.py extension I wrote.  

All the TCF packets end in \x03\x01 which I didn't see in the
documentation.

Did I just miss it?  What does it signify?
