--- Comment #88 from Richard Russo <freebsd@ruka.org> ---
Also, I had intended to include a link to a similar change in the Linux ker=
nel,
https://github.com/torvalds/linux/commit/96e0bf4b5193d0d97d139f99e2dd128763=
d55521
(Although the comments there say this behavior is consistent with the RFC, I
don't think it is consistent however, the RFC says, "If the ACK acks someth=
ing
not yet sent (SEG.ACK > SND.NXT) then send an ACK, drop the segment, and
return.")
