> Allow support for S-Tag + C-Tag VLAN traffic by disabling pruning when there
> are no 0x8100 VLAN interfaces currently created on top of the PF.
> When an 0x8100 VLAN interface is configured, enable pruning and only
> support single and double C-Tag VLAN traffic. If all of the 0x8100 interfaces
> that were created on top of the PF are removed via ethtool -K <iface> rx-
> vlan-filter off or via ip tools, then disable pruning and allow S-Tag + C-Tag
> traffic again.
> 
> Add VLAN 0 filter by default for the PF. This is because a bridge sets the
> default_pvid to 1, sends the request down to ice_vlan_rx_add_vid(), and we
> never get the request to add VLAN 0 via the 8021q module which causes all
> untagged traffic to be dropped.
