* RTE Mbuf Packet Types
*
* This file contains declarations for features related to mbuf packet
* types. The packet type gives information about the data carried by the
* mbuf, and is stored in the mbuf in a 32 bits field.
*
* The 32 bits are divided into several fields to mark packet types. Note that
* each field is indexical.
* - Bit 3:0 is for L2 types.
* - Bit 7:4 is for L3 or outer L3 (for tunneling case) types.
* - Bit 11:8 is for L4 or outer L4 (for tunneling case) types.
* - Bit 15:12 is for tunnel types.
* - Bit 19:16 is for inner L2 types.
* - Bit 23:20 is for inner L3 types.
* - Bit 27:24 is for inner L4 types.
* - Bit 31:28 is reserved.
*
* To be compatible with Vector PMD, RTE_PTYPE_L3_IPV4, RTE_PTYPE_L3_IPV4_EXT,
* RTE_PTYPE_L3_IPV6, RTE_PTYPE_L3_IPV6_EXT, RTE_PTYPE_L4_TCP, RTE_PTYPE_L4_UDP
* and RTE_PTYPE_L4_SCTP should be kept as below in a contiguous 7 bits.
*
* Note that L3 types values are selected for checking IPV4/IPV6 header from
* performance point of view. Reading annotations of RTE_ETH_IS_IPV4_HDR and
* RTE_ETH_IS_IPV6_HDR is needed for any future changes of L3 type values.
*
* Note that the packet types of the same packet recognized by different
* hardware may be different, as different hardware may have different
* capability of packet type recognition.
*
* examples:
* <'ether type'=0x0800
* | 'version'=4, 'protocol'=0x29
* | 'version'=6, 'next header'=0x3A
* | 'ICMPv6 header'>
* will be recognized on i40e hardware as packet type combination of,
* RTE_PTYPE_L2_ETHER |
* RTE_PTYPE_L3_IPV4_EXT_UNKNOWN |
* RTE_PTYPE_TUNNEL_IP |
* RTE_PTYPE_INNER_L3_IPV6_EXT_UNKNOWN |
* RTE_PTYPE_INNER_L4_ICMP.
*
* <'ether type'=0x86DD
* | 'version'=6, 'next header'=0x2F
* | 'GRE header'
* | 'version'=6, 'next header'=0x11
* | 'UDP header'>
* will be recognized on i40e hardware as packet type combination of,
* RTE_PTYPE_L2_ETHER |
* RTE_PTYPE_L3_IPV6_EXT_UNKNOWN |
* RTE_PTYPE_TUNNEL_GRENAT |
* RTE_PTYPE_INNER_L3_IPV6_EXT_UNKNOWN |
