Subject: [PATCH] i40e: fix vlan filtering
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.
