Detailed Description

EXPERIMENTAL: this API may change, or be removed, without prior notice

A structure used to configure hairpin binding.

Field Documentation

uint32_t peer_count

The number of peers.

Definition at line 1120 of file rte_ethdev.h.

uint32_t tx_explicit

Explicit Tx flow rule mode. One hairpin pair of queues should have the same attribute.

  • When set, the user should be responsible for inserting the hairpin Tx part flows and removing them.
  • When clear, the PMD will try to handle the Tx part of the flows, e.g., by splitting one flow into two parts.

Definition at line 1131 of file rte_ethdev.h.

uint32_t manual_bind

Manually bind hairpin queues. One hairpin pair of queues should have the same attribute.

  • When set, to enable hairpin, the user should call the hairpin bind function after all the queues are set up properly and the ports are started. Also, the hairpin unbind function should be called accordingly before stopping a port that with hairpin configured.
  • When clear, the PMD will try to enable the hairpin with the queues configured automatically during port start.
