mac80211-wip preview

[Johannes Berg <johannes@sipsolutions.net>]

Hi,

This is a more tentative preview, things are still subject to change.

The included patchsets and their status:
 * P2P Device work
   I posted this, I'll apply it when I get back unless I see any
   objections then :-)
 * some more cleanups, including the CSA cleanups
   I posted most of these I believe, and will also apply most of it when
   I get back
 * a brcmsmac patch that I posted -- I'm not going to apply it but I
   just wanted to do a random cleanup (the obsolete functions removal)
 * and channel context code of course!
   This is still WIP, I need to
   - address SMPS -- I might just do passive/active # of chains per
     channel context and let the driver sort out the rest, this gives it
     more information and flexibility
   - TX power -- I'm open to suggestions about how we should do this,
     technically the user setting could be per virtual interface, but do
     we care? I have a feeling it should be per channel since even 11h
     TX power reduction is defined for the entire channel

FWIW, multi-channel works in hwsim, but hasn't been tested with actual
drivers yet. If somebody wants to do that while I'm on vacation, the
code is all there in the mac80211-next/wip branch on git.kernel.org. :-)
