> VLAN filtering was always performed, even if hw_vlan_filter was disabled.
> During device initialization, default filter RTE_MACVLAN_PERFECT_MATCH
> was applied. In this situation, all incoming VLAN frames were dropped by the
> card (increase of the register RUPP - Rx Unsupported Protocol).
> 
> In order to restore default behavior, if HW VLAN filtering is activated, set a
> filter to match MAC and VLAN. If not, set a filter to only match MAC.
