These patches have been applied to the wpan-next tree and will be
part of the next pull request to net-next. Thanks!

Before I would add them to a pull request to net-next I would like to 
have an updated patchset for iwpan to reflect these scan changes. We 
would need something to verify the kernel changes and try to coordinate 
a new iwpan release with this functionality with the major kernel 
release bringing the feature.

Thanks again for your work.
