Johannes Berg 0f70f39846 cfg80211: "fix" 11d oops
This "fixes" the 11d oops I was seeing. This needs some more work but I
cannot work on it now.

This patch adds new NL80211_CMD_SET_WIPHY attributes
NL80211_ATTR_WIPHY_FREQ and NL80211_ATTR_WIPHY_SEC_CHAN_OFFSET to allow
userspace to set the operating channel (e.g., hostapd for AP mode).

Jouni Malinen bf8c1ac6d8 nl80211: Change max TX power to be in mBm instead of dBm
In order to be consistent with NL80211_ATTR_POWER_RULE_MAX_EIRP,
change NL80211_FREQUENCY_ATTR_MAX_TX_POWER to use mBm and U32 instead
of dBm and U8. This is a userspace interface change, but the previous
version had not yet been pushed upstream and there are no userspace
programs using this yet, so there is justification to get this change in
as long as it goes in before the previous version gets out.

Luis R. Rodriguez 14b9815af3 cfg80211: add support for custom firmware regulatory solutions
This adds API to cfg80211 to allow wireless drivers to inform
us if their firmware can handle regulatory considerations *and*
they cannot map these regulatory domains to an ISO / IEC 3166
alpha2. In these cases we skip the first regulatory hint instead
of expecting the driver to build their own regulatory structure,
providing us with an alpha2, or using the reg_notifier().

Luis R. Rodriguez 3f2355cb91 cfg80211/mac80211: Add 802.11d support
This adds country IE parsing to mac80211 and enables its usage
within the new regulatory infrastructure in cfg80211. We parse
the country IEs only on management beacons for the BSSID you are
associated to and disregard the IEs when the country and environment
(indoor, outdoor, any) matches the already processed country IE.

To avoid following misinformed or outdated APs we build and use
a regulatory domain out of the intersection between what the AP
provides us on the country IE and what CRDA is aware is allowed
on the same country.

A secondary device is allowed to follow only the same country IE
as it make no sense for two devices on a system to be in two
different countries.

In the case the AP is using country IEs for an incorrect country
the user may help compliance further by setting the regulatory
domain before or after the IE is parsed and in that case another
intersection will be performed.

CONFIG_WIRELESS_OLD_REGULATORY is supported but requires CRDA
present.

Luis R. Rodriguez 02ba0b3263 cfg80211: call_crda() won't tell us if CRDA was present
kobject_uevent_env() can return an error but it just tells us
if the uvent was built/sent or not, it doesn't tell us anything
about what happened in userspace, whether the udev rule was present
nor does it tell us if CRDA was present or not. So remove
the informative complaint about it assuming it will tell us
such things.

Note that you can determine if CRDA is present after loading cfg80211
by using:

is_old_static_regdom(cfg80211_regdomain)

but this doesn't account for possible user install after initial
boot, and also for when the user uses the static EU regulatory
domain.

Luis R. Rodriguez b8295acdc3 cfg80211: separate intersection section in __set_regdom()
So far the __set_regdom() code is pretty generic as the
intersection case is fairly straight forward; this will however
change when 802.11d support is added so lets separate intersection
code for now in preparation for 802.11d support.

This patch only has slight functional changes.

Luis R. Rodriguez 9c96477d10 cfg80211: Add regulatory domain intersection capability
There are certain scenerios where we require intersecting
two regulatory domains. This adds intersection support.
When we enable 802.11d support we will use this to intersect
the regulatory domain from the AP's country IE and what our
regulatory agent believes is correct for a country.

This patch enables intersection for now in the case where
the last regdomain was set by a country IE which was parsed
and the user then wants to set the regulatory domain. Since
we don't support country IE parsing yet this code path will not
be hit, however this allows us to pave the way for 11d support.

Intersection code has been tested in userspace with CRDA.
