I'm trying to get a better understanding of the TCP layer, so what I've done 
is isolated that part of the stack and simulated a client and a host.  To 
see if I've done it correctly, I need to compare the values they spit across 
to each other with correct values.

Does someone have a tcp dump of values for the tcp control block (tcpcb) and 
header values (tcpiphdr).

What would be awesome is if someone had snapshots of the tcp control block 
throughout the setup, established session and teardown and also the values 
of in the header.

For example:
When the client sends a SYN
tp->snd_wnd = 6;
tp->snd_cwnd = 36;
tp->rcv_wnd = 5;

ti->ti_seq = 234234;
ti->ti_ack = 3423;

OR even just a tcpdump.
