On June 1st, I was able to do my monthly laptop ZFS snap-shot/back-up

can't without the em0 interface stalling :-(
On a guess, I tried reverting SVN r335303 but that didn't help.

.. ad nauseum ..
"ifconfig em0 down; ifconfig em0 up" doesn't help.
Any hints?
Hi,
I'm not seeing any problems using em0/saturating upstream
using 12.0-CURRENT #0 r335979
