Andy,

Basically LGTM, so even in smartnic configs, the PF @ the host is
still privileged to
create/destroy VFs or provision MACs for them even if it is not the
e-switch manager
anymore?

Actually AFAIK this  can also work somehow otherwise, e.g a smartnic FW
"pushes" the VFs into the host w.o them being under a host admin directive.
