Subject: Panic during network initialization after r339583 -> r339639

Gory details in <http://www.catwhisker.org/~david/FreeBSD/head/r339639/>.

I snapped some screenshots, but can't associate using laptop's iwn(4)
(in stable/11, stable/12, or head/13) at the place I'm currently
staying.  (I may be able to at least get the screenshots uploaded to the
Web server later on today.)  But since I was able to get a dump, they
are probably not very interesting.

It looks (to my semi-trained eye) as if iflib is implicated --
partly because the backtrace mentions it (ref. frame #14 from the
backtrace in core.txt.8), and partly because I only saw the panic
on my laptop, the wired NIC for which is em(4), while my build
machine (which uses rl(4)) had no issues.

I'm happy to poke and/or test, but will need some direction to do so.

Peace,
david
