This draft provides the Yang data mode for TCP.

The draft is well written and is almost ready publication.  I verified the FSM
state machine and all states are listed.

Minor issues:
None

Major issues:
None

Nits:
I reviewed the TCP Yang data model and has a question related to the FSM state
machine.

Would it be possible to specify the TCP Header flags SYN, FIN, ACK, RST of BFD
FSM finite state machine Events and Transition.  I think this would be very
helpful for the TCP Yang model FSM state machine.  For each state you could
specify the flags set.

I think the TCP TCB (TCP Control Block) is missing in the Yang model. This is
important for troubleshooting TCP connection state.
