Hi David,

Great stuff!

Hmm, in fact, if we go that route then we can do dumping for vifs (by
wiphy I guess) since all this information is available in the kernel,
only GET_ASSOCIATION should need a callout. vif type can be dumped just
fine.

Yeah, but as we said, this really needs to tie in with any regulatory
stuff.

Sounds reasonable, needs automatic/... but for .11n it might need some
more things. Not sure.
