We are using igb(4) with vlan(4), tap(4) bundled into bridge(4).  The taps
are entries to bhyve guests.  These were built initially on FreeBSD 11.0
and have been recently uplifted to FreeBSD 11.1.  We have never had any
issues with these bridges, even under heavy load.

We do want to netmap/vale but not until it is maintainable via
freebsd-update (built into generic).

So based on what you have said, a bit more of a breakdown to determine the
culprit that is within the bridge might be needed, especially with VIMAGE
(though our FreeNAS jails use VIMAGE and bridges without breakage also).

Cheers,

Jason.
