> 
> For NEON vector of IXGBE PMD, introduce new flag PKT_RX_VLAN_STRIPPED to
> show the case that the VLAN is stripped from the VLAN tagged packet.
> 
> This is because that the old flag PKT_RX_VLAN_PKT only indicates that the
> packet is VLAN tagged, but cannot show whether VLAN is in m->vlan_tci or
> in the packet at present. So add new flag to show the vlan has been
> stripped by the hardware and its tci is saved in m->vlan_tci when vlan
> stripping is enabled in the RX configuration of the IXGBE PMD.
