Hi Julien,

With bug 211990 =
(https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D211990),
the main issue was that iSCSI disks did not disconnect properly, so that =
it was
impossible to reconnect to them without changing the target name or =
rebooting.

I saw that you worked-around the disconnection issue turning off jumbo =
frames.
But I would have liked to keep jumbo on : many iSCSI disks to come on =
this
server, and also a long-distance link to another server.

Thank you very much !
