We have been doing a lot of work in netlink/devlink to program the VF
settings before starting the VF driver

I've long thought it would be good to standardize a VF lifecycle in
Linux eg VFs start their life in some 'unconfigured' state and drivers
don't bind, then userspace can use the PF to perform configuration,
finally the driver can start on a configured VF

We are already doing this model for the mlx5 'sub function' interfaces
which have alot of analogs to both VFs and Intel's SIOV ADIs. It seems
to be working.
