I am wondering if there is support for such device in the ixgbe PMD. the dpdk nic bind script seems to see them correctly but when running testpmd with those ports, they always come with link status down.
>From the dpdk_nic_bind script (snip): Network devices using DPDK-compatible driver ============================================ 0000:03:00.0 'Ethernet Connection X552/X557-AT 10GBASE-T' drv=igb_uio unused= 0000:03:00.1 'Ethernet Connection X552/X557-AT 10GBASE-T' drv=igb_uio unused= And I am starting testpmd with this command line: ./testpmd -c 0x7 -n 4 -- -i I have enabled all the ixgbe debugging messages and I have noticed this messages when testpmd starts: PMD: ixgbe_device_supports_autoneg_fc(): Device 15ad does not support flow control autoneg I am using the latest dpdk on master branch as of today.
