Detailed Description
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.
