When running testpmd I find that there are no packets transmitted and the tx-error stat just keeps getting incremented wh= en a packet is transmitted. I did some further testing of different DPDK versions and found that the following commit is the one that stopped these cards working in a vSphere V= M: https://github.com/DPDK/dpdk/commit/34283fc94847f237677edd5909639503c605daeb When I revert this commit I find that i40e VFs on vSphere do work with DPDK 20.11. Steps to Reproduce: This can be reproduced with the following steps: - Add an XXV710 VF SR-IOV interface to a vSphere VM - Use testpmd to transmit packets on the vSphere VM (I used `testpmd -l 2,4= ,6 -- --stats-period=3D5 --forward-mode=3Dmac --port-topology=3Dloop`) Actual Results: The tx-error stats are incremented and no packets are transmitted. Expected Results: The packets should be transmitted. --=20 You are receiving this mail because: You are the assignee for the bug.=
