Cisco 9800 WLC - being discovered as a generic network device, no WiFI info

We are currently testing 9800 controllers (IOS-XE) in planning to replace our existing AireOS boxes.

Observium discovers and polls the 9800's fine, but they are discovered as generic network devices, not wireless, and present no WiFi related info. No information about connected access points, clients, WiFi statistics, etc. It's not very useful from a monitoring standpoint.

9800 specific MIBs attached.
