Hi, I've got a couple of 82598 dual NIC and I'm running into a number of issues. - When enabling the port DPDK/testpmd report: Configuring Port 0 (socket 0) ixgbe_dev_rx_queue_start(): Could not enable Rx Queue 0 Port 0: 00:1B:21:45:9F:1B - After the port is configured and started, DPDK always reports the link speed of 0 and status as down, despite the switch having the link light come on when the port is enabled (link status and speed is reported correctly when the device is used by the kernel driver). testpmd> show port info all ********************* Infos for port 0 ********************* MAC address: 00:1B:21:45:9F:1B Device name: 0000:01:00.0 Driver name: net_ixgbe Connect to socket: 0 memory allocation on the socket: 0 Link status: down Link speed: 0 Mbps Link duplex: half-duplex - A very high RX error count is reported in testpmd (start tx_first 10; stop): ---------------------- Forward statistics for port 0 ---------------------- RX-packets: 0 RX-dropped: 0 RX-total: 0 RX-error: 29887428216 RX-nombufs: 0 TX-packets: 0 TX-dropped: 65 TX-total: 65 ---------------------------------------------------------------------------- ---------------------- Forward statistics for port 1 ---------------------- RX-packets: 0 RX-dropped: 0 RX-total: 0 RX-error: 29887428216 RX-nombufs: 0 TX-packets: 0 TX-dropped: 65 TX-total: 65 ---------------------------------------------------------------------------- I noticed that there was an email thread from a few years back that described similar issues with the 82598 cards. http://mails.dpdk.org/archives/dev/2016-January/032067.html Any advice on how I could further troubleshoot these issues? This happens when running as both root and a non-privileged user. Regards, Michael Barker.
