https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D173444 --- Comment #6 from marka@isc.org --- (In reply to Hiren Panchasara from comment #5) My test system died years ago but I believe that it still is a problem. It should be trivial to check. create a IPv6 TCP socket. set IPV6_USE_MIN_MTU=3D1 using setsockopt connect to a data sink write 1400 bytes to the socket in a single operation Examine the packets sent with tcpdump. There should be no fragmented packets being sent as TCP is supposed to take into account MTU information. Mark --=20 You are receiving this mail because: You are the assignee for the bug.=
