- * 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.
