Thanks for doing this. Your current version has couple show stopper
issues.
First, the slave device is instantly taking over the slave.
This doesn't allow udev/systemd to do its device rename of the slave
device. Netvsc uses a delayed work to workaround this.
Secondly, the select queue needs to call queue selection in VF.
The bonding/teaming logic doesn't work well for UDP flows.
Commit b3bf5666a510 ("hv_netvsc: defer queue selection to VF")
fixed this performance problem.
Lastly, more indirection is bad in current climate.
I am not completely adverse to this but it needs to be fast, simple
and completely transparent.
