Missinterpretion on my side.

Well - considering USB high speed you have 480MBit/s half duplex
with much USB overhead.
Even if everthing performce ideally, you are limited.

Yes - you have a physical base interface and configure virtual ones
attached to that.
This is used quite ofter and tested very well.
See ifconfig manpage about VLAN configuration.
But as I already said - you need a switch, which understands VLAN tags.
You also need a physical interface which is capable of trasfering
oversized Packets, VLAN_MTU feature listed in ifconfig -m.
