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 \| RTE\_PTYPE\_INNER\_L4\_UDP.
