PfSense 2.3.2 not detecting TP link N900

[Brosef_Stalin]

I'm trying to set up a pfSense router to serve as a wireless access point, using this PCIe wireless NIC: https://wikidevi.com/wiki/TP-LINK_TL-WDN4800

It uses an Atheros chipset, and from what I can tell should be supported in pfSense 2.3.2, since support was added with FreeBSD 10, but I don't see the interface in the menus or in pciconf:

Anyone know why I'm not seeing an 'ath0' interface?
