> be treated as any other untrusted VF, and the PF will reset the VF.

> If a designated DCF requests AVF functionality from the same VF (VF-ID) without
> the DCF gracefully relinquishing the DCF functionality first (by way appropriate
> virtchnl message exchanges), the PF shall remove all the switch filters that were
