Description (partial)

A WLC may report rogue devices with the following implausible characteristics:

* rogue reported by multiple APs which are in geographically distant locations
* rogue reported on non-monitored channels such as 16, 80, 96, 240
* rogue MAC addresses look invalid - unassigned OUIs; many ending with 00:00, etc.

Potentially a very large number of these invalid rogues is reported.

Rogue detection is enabled.
