Hello, We are running ESXi 6.0 U1 (build 3380124) on DELL PowerEdge R640. We are using Intel X710 10Gbe 2P NICs configured in SR-IOV mode and attached as VFs to Centos guests. On Host we installed the needed X710 Driver (i40e version 2.6.0) and Firmware (18.0.0) per VMware compatibility matrix.
Inside a VM, we are using DPDK version 2.2.0 (also tried latest version) as an interface to send/receive traffic to/from VFs. Main problem: 1. With DPDK 2.2.0 a. The PF is recognized as non-DPDK PF, when there is a failure to "disable HW CRC strip" b. The ports inside a VM are recognized as half duplex and the traffic is partial. 2. With latest DPDK versions (tried 17.05, 17.08, 18.02) a. There is a delay of ~8160 usec between sent packets. Could you please advise, what should be the right compatibility between: ESXi version <-> X710 NIC Firmware / Driver <-> DPDK version, and anything else, if needed, to make the above work? (*) As a note, we never experienced such issues on HP with 82599 Intel NICs (ixgbe) with the same DPDK (2.2.0) on the same Centos VM. Hope for your assistance. Thank you, Yan
