Once tunnel packet type(RTE_PTYPE_TUNNEL_xxx) identified,
PKT_RX_IP_CKSUM_XXX and PKT_RX_L4_CKSUM_XXX represent checksum result of
inner headers, outer L3 and L4 header checksum are always valid as soon
as tunnel identified. If no tunnel identified, PKT_RX_IP_CKSUM_XXX and
PKT_RX_L4_CKSUM_XXX represent checksum result of outer L3 and L4
headers.
