ConnectX-3 VFs are not working on pfSense 2.4.5 on PVE 6.3

The project builds up stout router with SR-IOV is now starting up!

That being so I tried to create a pfSense 2.4.5-p1 VM on Proxmox VE 6.3-2 with ConnectX-3 VFs by PCI pass-through, but it didn't recognise them properly…😇

Some error logs are recorded in dmesg such as “pcib1: failed to allocate initial I/O port window: 0xd000-0xdfff” and “pcib1: Failed to allocate interrupt for PCI-e events”, and the VFs aren't listed up with pciconf -lv command. That means device probing fails anyways, I guess.

The pfSense 2.4 is based on FreeBSD 11.3-RELEASE. It is old-ish, so I tried newer pfSense 2.5 which is under development and is based on FreeBSD 12-STABLE.

The system recognises the VFs properly and mlxen devices are created though the former error occurs same as usual. I don't know why two mlxen are identified as mlxen0 and mlxen2 even though I pass through sequence number of VFs. It's weird, but I'll settle for this for now.

It seems mlx4 modules are embedded into a kernel of pfSense 2.4.5 or 2.5.

It is out of the question if NIC is out of order, so I decided to use developing pfSense 2.5. There is no doubt stable pfSense 2.5 will be released at some future date.
