I don't think we should abstract it.
A one command that can set one or multiple fields of the config space is fine.

That is fine,
It is just that the flow filter commands may be different for ingress and
egress direction of the VF.
The command that we are adding does not have concept of switch ports, because
there is no switch.
For eswitch case, you would define more commands that will have switch ports...

It should be through the flow filter queue so that it can be performant like
nic tx/rxq which has dedicated role.
For switch use case command formats or fields needs extension.
