This is likely a quick and easy question that I can’t seem to find a concise answer to… The literature suggests SR-IOV and 802.1q are features that should work, and there is no reference to interactions, but…
Do ConnectX-6 Dx, when in SR-IOV mode, support VMs sending 802.1q tagged packets via the VFs? And if so, are there particular firmware versions or adapter settings that need to be configured beyond the basic SR-IOV setup?
I’m seeing a case where it looks like the adapter is dropping the packets sent by the VM. Similarly, packets from the switch seem to vanish after heading towards the card. I’m working in a remote enviornment, so getting a sniffer in the middle to validate this is a bit tricky, so even a simple “No, this doesn’t work” or “Yes, it should work, I use it…” should be enough to let me know if its worth spending time playing with it.
There also appears to be some [old] language about enabling trust on the VFs, but no clear way to enable it with VMWare.
