Hi, We are currently using the Intel X710 10Gb NIC adapter. Of late, with our customers, we are seeing a continuous flapping of the 10G port and in the kernel logs we are observing - Aug 31 12:38:34 kernel: i40e 0000:12:00.0 ens1f0: tx_timeout: VSI_seid: 387, Q 14, NTC: 0x120, HWB: 0x1e2, NTU: 0x1e2, TAIL: 0x1e2, INT: 0x0 Aug 31 12:38:34 kernel: i40e 0000:12:00.0 ens1f0: tx_timeout recovery level 1, hung_queue 14

We are currently using 2.22.18 of the i40e driver, our NIC firmware is at 10.54.5, and the private flags are - Private flags for ens1f0: MFP : off total-port-shutdown : off LinkPolling : off flow-director-atr : on veb-stats : off hw-atr-eviction : off link-down-on-close : off legacy-rx : off disable-source-pruning : off disable-fw-lldp : on rs-fec : off base-r-fec : off multiple-traffic-classes: off vf-vlan-pruning : off vf-source-pruning : on vf-true-promisc-support : off Has anyone seen this issue before?Regards,Sriram | | ReplyForward | _______________________________________________ E1000-devel mailing list E1000-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/e1000-devel To learn more about Intel Ethernet, visit https://community.intel.com/t5/Ethernet-Products/bd-p/ethernet-products
