cc32abd494 mac80211: move channel switch code
The channel switch code is currently in the spectrum
management file, where arguably it belongs. However,
it is for managed mode only and uses the structures
for that mode only so having it in a more generic
file can be confusing. Additionally, my next patch
gets simpler with the code here.

When/if we ever implement this for IBSS or mesh then
we will need to rework the structures it uses anyway
at which point we could move the code back.

d323655372 cfg80211: clean up includes
Trying to separate header files into net/wireless.h and
net/cfg80211.h has been a source of confusion. Remove
net/wireless.h (because there also is the linux/wireless.h)
and subsume everything into net/cfg80211.h -- except the
definitions for regulatory structures which get moved to
a new header net/regulatory.h.

The "new" net/cfg80211.h is now divided into sections.

There are no real changes in this patch but code shuffling
and some very minor documentation fixes.

I have also, to make things reflect reality, put in a
copyright line for Luis to net/regulatory.h since that
is probably exclusively written by him but was formerly
in a file that only had my copyright line.

469002983f mac80211: split IBSS/managed code
This patch splits out the ibss code and data from managed (station) mode.
The reason to do this is to better separate the state machines, and have
the code be contained better so it gets easier to determine what exactly
a given change will affect, that in turn makes it easier to understand.

This is quite some churn, especially because I split sdata->u.sta into
sdata->u.mgd and sdata->u.ibss, but I think it's easier to maintain that
way. I've also shuffled around some code -- null function sending is only
applicable to managed interfaces so put that into that file, some other
functions are needed from various places so put them into util, and also
rearranged the prototypes in ieee80211_i.h accordingly.

00d3f14cf9 mac80211: use cfg80211s BSS infrastructure
Remove all the code from mac80211 to keep track of BSSes
and use the cfg80211-provided code completely.

a8302de934 mac80211: Handle power constraint level advertised in 11d+h beacon
This patch uses power constraint level while determining the maximum
transmit power, there by it makes sure that any power mitigation
requirement for the channel in the current regulatory domain is met.

1acc97b63a mac80211: 802.11w - Do not force Action frames to disable encryption
When sending out Action frames, allow ieee80211_tx_skb() to send them
without enforcing do_not_encrypt. These frames will be encrypted if
MFP has been negotiated.

e50db65c0d mac80211: move frame TX function
The ieee80211_sta_tx function isn't MLME code any more,
it's getting used by a lot of code. Move it to utils and
rename it to ieee80211_tx_skb.

39192c0bcf mac80211: move spectrum management code out
Like the HT code, this doesn't depend on the STA-mode implementation
and can be handled entirely independently. There's only stub code
for now, but when it gets filled having it in its own file will be
beneficial.
