Detailed Description

Warning
EXPERIMENTAL: this structure may change without prior notice.

A structure used to configure an Rx packet segment to split.

If RTE_ETH_RX_OFFLOAD_BUFFER_SPLIT flag is set in offloads field, the PMD will split the received packets into multiple segments according to the specification in the description array:

Field Documentation

◆ mp

struct rte_mempool* mp

Memory pool to allocate segment from.

Definition at line 1044 of file rte_ethdev.h.

◆ length

uint16_t length

Segment data length, configures split point.

Definition at line 1045 of file rte_ethdev.h.

◆ offset

uint16_t offset

Data offset from beginning of mbuf data buffer.

Definition at line 1046 of file rte_ethdev.h.

◆ proto_hdr

uint32_t proto_hdr

proto_hdr defines a bit mask of the protocol sequence as RTE_PTYPE_*. The last RTE_PTYPE* in the mask indicates the split position.

If one protocol header is defined to split packets into two segments, for non-tunneling packets, the complete protocol sequence should be defined. For tunneling packets, for simplicity, only the tunnel and inner part of complete protocol sequence is required. If several protocol headers are defined to split packets into multi-segments, the repeated parts of adjacent segments should be omitted.
