Detailed Description

A structure used to configure an Ethernet port. Depending upon the RX multi-queue mode, extra advanced configuration settings may be needed.

Field Documentation

◆ link_speeds

uint32_t link_speeds

bitmap of ETH_LINK_SPEED_XXX of speeds to be used. ETH_LINK_SPEED_FIXED disables link autonegotiation, and a unique speed shall be set. Otherwise, the bitmap defines the set of speeds to be advertised. If the special value ETH_LINK_SPEED_AUTONEG (0) is used, all speeds supported are advertised.

Examples:
examples/ip_pipeline/link.c, and examples/pipeline/obj.c.

Definition at line 1294 of file rte_ethdev.h.

◆ rxmode

struct rte_eth_rxmode rxmode

◆ txmode

struct rte_eth_txmode txmode

◆ lpbk_mode

uint32_t lpbk_mode

Loopback operation mode. By default the value is 0, meaning the loopback mode is disabled. Read the datasheet of given ethernet controller for details. The possible values of this field are defined in implementation of each driver.

Definition at line 1303 of file rte_ethdev.h.

◆ rss_conf

struct rte_eth_rss_conf rss_conf

Definition at line 1310 of file rte_ethdev.h.

◆ dcb_rx_conf

struct rte_eth_dcb_rx_conf dcb_rx_conf
