[PATCH v3] ethdev: add packet type matching item

[Alexander Kozyrev <akozyrev@nvidia.com>]

Add RTE_FLOW_ITEM_TYPE_PTYPE to allow matching on
L2/L3/L4 and tunnel information as defined in mbuf.

To match on RTE_PTYPE_L4_TCP and RTE_PTYPE_INNER_L4_UDP:
  flow pattern_template 0 create pattern_template_id 1
    ingress template ptype packet_type mask 0x0f000f00 / end
  flow queue 0 create 0 template_table 1
    pattern_template 0 actions_template 0
    pattern ptype packet_type is 0x02000100 / end
    actions queue index 1 / end
