Well, now I'm curious, so let's break it down. What was the context of
the discussion? I assume by "control bits," he meant what Wireshark
calls the "Flags" which are Nonce, Congestion Window Reduced, ecn-echo,
URGent, ACKnowledgement, PuSH, reset, SYNchronize and FINish bits (and a
few reserved for future use). The only other things in a TCP segment
are shown here:
