> Currently if the host disables VLAN offloads on the VF by not setting the
> VIRTCHNL_VF_OFFLOAD_VLAN capability bit we will still honor VF VLAN
> configuration messages over VIRTCHNL. These messages (i.e. enable/disable
> VLAN stripping and VLAN filtering) should be blocked when the feature is not
> supported. Fix that by adding a helper function to determine if the VF is
> allowed to do VLAN operations based on the host's VF configuration.
> 
> Also, mirror the VF communicated capabilities in the host's VF configuration.
