My commit is inside the FreeBSD kernel, so you just r= ebuild the=C2=A0`kernel`, and
you don't need to rebuild the `= world`.

I've just realised, your commit didn't land in main until 17th Sept= so I'll need
to buildworld etc on the bhyve *host* as it was last built on the 8th. Woul= d this
make a difference?

The new vms are -current and have been built over the last
couple of days, from fresh sources, so these will have your changes.

The iperf3 destination is stable/14-n268832 amd64 1401502 1401502.
