I find it a bit frustrating that it takes so many different commands
to find the information I'm looking for.

It looks like I'll need to integrate at least:

The information for the in-use BSS from 'scan dump', the info
from 'info', 'survey dump' for the active channel,
'station dump' (with additional of at least the counters that
used to be found in /proc/net/wireless),

If I were only doing one or two STA interfaces, that's not so bad,
but if I want to do hundreds, and update info relatively often,
that's going to be a lot of overhead!

Thanks,
Ben
