[iwinfo PATCH 1/2] iwinfo: add support for indoor only chan restriction

[Seo Suchan]

Which will get priority in DFS or indoor channels? will it have setting 
to enable DFS for such channel? well we can't really enforce 
'indoorness' of out target, isn't it? Or will we have per device target 
config for 'this will be outdoor' ?
