https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=174535 Hiren Panchasara <hiren@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |hiren@FreeBSD.org --- Comment #2 from Hiren Panchasara <hiren@FreeBSD.org> --- Unsure if you are still chasing this but I am a bit lost on what you are trying to do. If you are trying to trigger fast-retransmit on 2 dupacks instead of 3, easiest way is to change 'const int tcprexmtthresh = 3' in tcp_input.c About tcpdump showing packet size > MSS, it usually happens with tso/lro. (Also providing actual pcaps help in such situations.) -- You are receiving this mail because: You are the assignee for the bug.
