NAME

rte_eth_recycle_rxq_info

SYNOPSIS

#include <rte_ethdev.h>

Data Fields


struct rte_mbuf ** mbuf_ring
struct rte_mempool * mp

uint16_t * receive_tail
uint16_t mbuf_ring_size
uint16_t refill_requirement

Detailed Description

Warning

EXPERIMENTAL: this structure may change without prior notice.

Ethernet device Rx queue information structure for recycling mbufs. Used to retrieve Rx queue information when Tx queue reusing mbufs and moving them into Rx mbuf ring.

Field Documentation

struct rte_mbuf** mbuf_ring

mbuf ring of Rx queue.

Definition at line 1896 of file rte_ethdev.h.

struct rte_mempool* mp

mempool of Rx queue.

Definition at line 1897 of file rte_ethdev.h.

uint16_t* refill_head

head of Rx queue refilling mbufs.

Definition at line 1898 of file rte_ethdev.h.

uint16_t* receive_tail

tail of Rx queue receiving pkts.

Definition at line 1899 of file rte_ethdev.h.

uint16_t mbuf_ring_size

configured number of mbuf ring size.

Definition at line 1900 of file rte_ethdev.h.

uint16_t refill_requirement

Requirement on mbuf refilling batch size of Rx mbuf ring. For some PMD drivers, the number of Rx mbuf ring refilling mbufs should be aligned with mbuf ring size, in order to simplify ring wrapping around. Value 0 means that PMD drivers have no requirement for this.
