Depending upon the Rx multi-queue mode, extra advanced configuration settings may be needed. Definition at line 1542 of file rte_ethdev.h. Field Documentation uint32_t link_speeds bitmap of RTE_ETH_LINK_SPEED_XXX of speeds to be used. RTE_ETH_LINK_SPEED_FIXED disables link autonegotiation, and a unique speed shall be set. Otherwise, the bitmap defines the set of speeds to be adver- tised. If the special value RTE_ETH_LINK_SPEED_AUTONEG (0) is used, all speeds supported are advertised.

Definition at line 1551 of file rte_ethdev.h. 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 de- tails. The possible values of this field are defined in implementation of each driver.
