freebsd stable - Aug 2018 - VNET related kernel panic on jail startup with epairs on 11-STABLE

Hi all!

One of out users observed an VNET related kernel panic with epairs in
a jail. Seems like some of the
vnet related patches does not gets backported to 11-STABLE (they are
marked as MFC candidate):
SVN r330000 and r313168, these are for the panic fix.

The other nice to have commit would be the r333885 commit, to fix
ctfconvert related build errors.

Well would be great for a start to (a) email virtualisation@ as well, 
(b) include a panic message, backtrace or other related information to 
deduce anything about the possible bug, (c) and not to conflate it with 
another totally unrelated MFC request.

So what makes you think it?s related to tcp fast open?
