Well actually you can. Dont be fooled by the interface name, vlan10
doesnt have to have the tag of 10. A nice way to do it is use the vlan
automatic creation, create the interfaces em0.1, em0.2, em0.3, [...]
em1.1, em1.2, em1.3, [...] and the tag and parent will get set up for
you.

ifconfig em0.1 create
ifconfig em0.2 create
ifconfig em0.3 create
and so on.
