I40e driver on VmWare for the X710 is heavily flawed when offloading and using jumbo frames.Disable all offload and run 1500MTU, then its rocksolid.
What about jumbo frames?
Do you have the latest firmware?Can you find anything in the logs?I have an X710-T4 which runs fine so far (virtualized), except for suricata because of the jumbo frames. https://forum.opnsense.org/index.php?topic=22942.0
Sorry, I meant the NIC firmware itself.You should probably see something in System -> Logfiles -> General if there are some hardware/driver issues.
