WLC Old Licensing

For the longest time before, Cisco had 2 separate SKUs for Base and PLUS licenses on WLC but it all changed with the 6.0.196 code.

"Before 6.0.196, licenses were separated into BASE and PLUS types.—With 6.0.196 and all later code (including 7.0 releases), all features included in a Wireless LAN Controller Wplus license are now included in the base license."
