5ce543d148 cfg80211: Restore orig channel values upon disconnect
When we restore regulatory settings the world regulatory domain
is properly reset on cfg80211 (or user prefered regulatory domain)
but we were never setting back channel values for drivers that use
WIPHY_FLAG_CUSTOM_REGULATORY. Set these values up again by using
the orig_ channel parameters.

This fixes restoring custom regulatory settings upon disconnect
events.

061acaae76 cfg80211: allow following country IE power for custom regdom cards
By definition WIPHY_FLAG_STRICT_REGULATORY was intended to allow the
wiphy to adjust itself to the country IE power information if the
card had no regulatory data but we had no way to tell cfg80211 that if
the card also had its own custom regulatory domain (these are typically
custom world regulatory domains) that we want to follow the country IE's
noted values for power for each channel. We add support for this and
document it.

This is not a critical fix but a performance optimization for cards
with custom regulatory domains that associate to an AP with sends
out country IEs with a higher EIRP than the one on the custom
regulatory domain. In practice the only driver affected right now
are the Atheros drivers as they are the only drivers using both
WIPHY_FLAG_STRICT_REGULATORY and WIPHY_FLAG_CUSTOM_REGULATORY --
used on cards that have an Atheros world regulatory domain. Cards
that have been programmed to follow a country specifically will not
follow the country IE power. So although not a stable fix distributions
should consider cherry picking this.

Currently, each AP interface will send multicast
traffic if any interface has a station entry even
if that station entry is allocated only. With the

by adding a counter that counts each authorized

the correct interface has at least one authorized
station.

d9a7ddb05e mac80211: refactor station state transitions
Station entries can have various states, the most
important ones being auth, assoc and authorized.
This patch prepares us for telling the driver about
these states, we don't want to confuse drivers with
strange transitions, so with this we enforce that
they move in the right order between them (back and
forth); some transitions might happen before the
driver even knows about the station, but at least
runtime transitions will be ordered correctly.

As a consequence, IBSS and MESH stations will now
have the ASSOC flag set (so they can transition to
AUTHORIZED), and we can get rid of a special case
in TX processing.

When freeing a station, unwind the state so that
other parts of the code (or drivers later) can rely
on the transitions.
