Update: can't find any way to panic a stock 8.1-RC2 it appears. After
bumping the date in our supfile to RC2, it appears most of the panics
disappear. The only remaining situation that panics is when plugging
it directly into a HP laptop, but it doesn't appear to do so with
FreeBSD's default settings. I suspect this is from some non-default
setting we use in pfSense, just haven't figured out what that is. The
actual e1000 code isn't modified in any way from stock FreeBSD.

It's not as easy to trigger with default/normal settings as I
initially thought, now trying to figure out what can be changed to
make that happen, or what difference in configuration is causing it.
