Fix dpdk-input check for VLAN packets including VLAN strip case
For DPDK-16.11 or later, use packet_type to check packets with VLAN tags. For earlier versions of DPDK, keep using ol_flags but include PKT_RX_VLAN_STRIPPED bit as part of the VLAN tags check. Change-Id: Ic4ad8f04e44658dc0a99de0232fdc949cfa13e93 Signed-off-by: John Lo <loj@cisco.com>
