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.p= atch 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. -Dustin
