Hmmm, yes, I suppose as the SYN consumes 1 sequence number, we should be
doing that there.  Will add it to the list of little things to fix!  All
other states call tcp_receive() which adjusts snd_buf appropriately, but
in SYN_SENT you're not going to get any data, so this was obviously
deemed unnecessary.

Out of interest, did you spot this because of a problem, or just notice
it when reading through the code?

Thanks
