A simpler way to use a "vlan" with -device is "-device e1000,vlan=0".
How is that related to hubport?

Well, netdevs can't be connected to a netdev in general, and hubport is
one. You can connect up to one device model to a netdev. I figure you
can additionally connect any number of old-style -net thingies to it,
whether they are NICs or not. Correct?

I'm afraid you missed netdev_add in hmp-command.hx.
