Hi everyone,

Just to notify you about the pull request #1204 on Github:
https://github.com/nmap/nmap/pull/1204

Nmap currently discards SYN-ACK packets having the TCP Fast Open option
(RFC 7413) set. Thus leading to false negative results.
This patch implements the support of this option, fixing the false
negative.
