[PATCH v3 0/6] Enable additional channels for use

[Ilan Peer <ilan.peer@intel.com>]

This set addresses comments from Luis:

1. Added a regulatory flag that can be used by drivers to disable the P2P
   GO relaxation.
2. Renamed the configuration option to CONFIG_CFG80211_REG_P2P_GO_RELAX.
3. Some code cleanups.

------

As before, this series addresses the option of enabling additional channels for
use based on the following relaxations:

1. Indoor operation, where a device can use channels requiring indoor
   operation, subject to that it can guarantee indoor operation.
2. Concurrent GO operation, where devices may instantiate a P2P GO
   while they are under the guidance of an authorized master.

The series includes:

* Some clarification (mainly in documentation) about the intended usage of
  channels marked as INDOOR_ONLY and CONCURRENT GO.
* Mapping of NL80211_RFF_NO_OUTDOOR to NL80211_CHAN_INDOOR_ONLY
* Support for a user hint that the platform is operating in an indoor
  environment, i.e., channel marked as INDOOR_ONLY can be used.
* Allow initiating radiation on channel marked with INDOOR_ONLY also
  for scanning an frame injection in monitor mode.
* Some additional fixes for comments I got.

Following is an example of a possible channel map that can be used to allow
the INDOOR_ONLY and CONCURRENT_GO relaxations. Note that:

* Channels 12,13 are marked as Concurrent GO, so even in the lack of exact
  information about the current regulatory domain, these channels can be used
  for GO instantiation based on the concurrent GO relaxation.
* The above is also true for channels 149-165 (a.k.a U-NII 3).
* Channels 36-48 (a.k.a thee U-NII 1), are marked both with Concurrent GO and
  indoor only. While the Concurrent GO can be used as described above, the
  indoor only setting allows to use these channels given the platform is
  identified as an indoor one, i.e., media server.
