[RFC PATCH] libertas: turn radio off when down

[elw at stderr.org]

Question.

How is this intended to interact with the mesh connectivity intended for 
the laptops?  I'm of the understanding that the mesh being powered and on 
is more or less a baseline design feature of the XO-as-platform.

Or is this an "airplane mode" feature that's going to get a button-push or 
other widget activation to activate?

I fully support the notion of making it possible to quickly and easily 
disable the radio, as well as mesh-y bits, saving power and reducing RF in 
situations where one is either clearly out-of-contact or prohibited from 
emitting excess RF energy, but I would want it to be:

1) very difficult to do by accident

2) give some indication that the radio is currently off, making it easy to
    quickly re-enable the radio.

What's the plan for UI for this?
