This means we have play with RIDs directly to control extended scan 
options until HostAP driver and WE supports it completely

Do you know of any RIDs which may be used to manipulate  probe_delay, 
min_channel_time and ,max_channel_time. Because in prism manual, I could 
not find any RIDs useful for above options.

Also do you know of any other driver and or wireless tools which 
actually have implemented this extended scan request of WE-18.
