Good, I like it.

Yes, that's useful to have, absolutely.
Would it be possible to mark TFO connections when they were NOT accepted as
well? That could be helpful, because right now I am not sure how I would find
failed TFO connections (except looking for SYN/ACK packets that fail). Or is
there an expert info that tells me that a connection used TFO and I can use the
field existence of the "accepted" TFO to check for it's absence to find failed
connections?
Unfortunately I have no example pcap for that scenario, so maybe this
functionality has to come as a later patch?
Cheers,
Jasper
