Hey there,
I think you will faceing a lot of trouble with this.
Was looking for the same thing for a kind of acceesspoint virtualization…
kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1005256
For VMware here they describe that u are able to send traffic to the wireless device and back. But the Host will only recognize a wired connection.
So one solution could be, to make all settings for the wireless card on the virtualization server (would mean to configure the server as a Access Point) and bridge all traffic to the host.
According to this, you need to do all the hostapd configuration on your own… Really a pain in the a**...
So pfsense will not recognize, that you attached an wireless adapter but another wired connection. The same goes for proxmox and KVM.
If you have a working solution, I really would appreciate if you could give us a little how to.
Edit
Found some blogs where people tried to achieve our goal with XEN an PCI Passthrough to HVM's. But therefore you would need hardware supporting VT-d
