Installed a PCIx4 Intel Chip WiFi card after initial Proxmox setup.
Cannot see WiFi card under network devices in Proxmox, but can do raw PCI Pass Thru to VM.
With PCI Pass Through to Linux VM (OpnSense FreeBSD), WiFi card is detected and driver is loaded, dmesg below.

But the device does not appear under ifconfig? Is there something different I should be doing here because the device is coming in pass through? Any pointers would be greatly appreciated. Thank you.
 
I've found the problem! The Wi-Fi card was actually PCIe, not PCI and the VM was configured as i440fx which only supports PCI passthrough. The solution was to re-build the VM as a q35 chipset machine that supports PCIe.
