> VFs by default are able to see all tagged traffic regardless of trust and VLAN
> filters. Based on legacy devices (i.e. ixgbe, i40e), customers expect VFs to
> receive all VLAN tagged traffic with a matching destination MAC.
> 
> Add an ethtool private flag 'vf-vlan-pruning' and set the default to off so VFs
> will receive all VLAN traffic directed towards them. When the flag is turned on,
> VF will only be able to receive untagged traffic or traffic with VLAN tags it has
> created interfaces for.
> 
> Also, the flag cannot be changed while any VFs are allocated. This was done to
> simplify the implementation. So, if this flag is needed, then the PF admin must
> enable it. If the user tries to enable the flag while VFs are active, then print an
> unsupported message with the vf-vlan-pruning flag included. In case multiple
> flags were specified, this makes it clear to the user which flag failed.
