So similar to the others, kind of.  Using the original
https://reviews.freebsd.org/D26418 patch, everything seems to work
fine.  Using the newer
http://people.freebsd.org/~kp/0001-bridge-Cope-with-if_ioctl-s-that-sleep.patch
patch, byhve VMs on the bridge attached to the igb/em(5) interfaces
don't pass traffic.  The bhyve VMs on the bridge attached to the
cxgbe(4) interfaces, however, work fine.
