While using DPDK, the x540 VFs are detected as 1G devices. The information of port 0 by PMD driver is this: PMD: eth_ixgbevf_dev_init(): port 0 vendorID=0x8086 deviceID=0x1515 mac.type=ixgbe_mac_82599_vf To check the link speed, I used this simple code: struct rte_eth_link rte_eth_link; rte_eth_link_get(0, &rte_eth_link); and the value of "rte_eth_link.link_speed" is ETH_LINK_SPEED_1000. Why is DPDK detecting the VF as 1G device and not 10G? Can I change this behavior? Thanks for your time. Regards Umar
