By default it's enabled with a non-zero value. 0 disables F-RTO.
tcp_fwmark_accept - BOOLEAN
If set, incoming connections to listening sockets that do not have a
socket mark will set the mark of the accepting socket to the fwmark of
the incoming SYN packet. This will cause all packets on that connection
(starting from the first SYNACK) to be sent with that fwmark. The
listening socket's mark is unchanged. Listening sockets that already
have a fwmark set via setsockopt(SOL_SOCKET, SO_MARK, ...) are
unaffected.
Default: 0
tcp_invalid_ratelimit - INTEGER
Limit the maximal rate for sending duplicate acknowledgments
