nl80211: add power save commands
The most needed command from nl80211, which Wireless Extensions had,
is support for power save mode. Add a simple command to make it possible
to enable and disable power save via nl80211.
I was also planning about extending the interface, for example adding the
timeout value, but after thinking more about this I decided not to do it.
Basically there were three reasons:
Firstly, the parameters for power save are very much hardware dependent.
Trying to find a unified interface which would work with all hardware, and
still make sense to users, will be very difficult.
Secondly, IEEE 802.11 power save implementation in Linux is still in state
of flux. We have a long way to still to go and there is no way to predict
what kind of implementation we will have after few years. And because we
need to support nl80211 interface a long time, practically forever, adding
now parameters to nl80211 might create maintenance problems later on.
Third issue are the users. Power save parameters are mostly used for
debugging, so debugfs is better, more flexible, interface for this.
For example, wpa_supplicant currently doesn't configure anything related
to power save mode. It's better to strive that kernel can automatically
optimise the power save parameters, like with help of pm qos network
and other traffic parameters.
Later on, when we have better understanding of power save, we can extend
this command with more features, if there's a need for that.

cfg80211/mac80211: allow registering for and sending action frames
This implements a new command to register for action frames

the socket can be closed for that.
Frames that are not registered for will not be forwarded
to userspace and will be rejected by the kernel, the
cfg80211 API helps implementing that.
Additionally, this patch adds a new command that allows
doing action frame transmission from userspace. It can be
used either to exchange action frames on the current
operational channel (e.g., with the AP with which we are
currently associated) or to exchange off-channel Public

mac80211: allow station add/remove to sleep
Many drivers would like to sleep during station
addition and removal, and currently have a high
complexity there from not being able to.
This introduces two new callbacks sta_add() and
sta_remove() that drivers can implement instead
of using sta_notify() and that can sleep, and
the new sta_add() callback is also allowed to
fail.
The reason we didn't do this previously is that
the IBSS code wants to insert stations from the
RX path, which is a tasklet, so cannot sleep.
This patch will keep the station allocation in
that path, but moves adding the station to the
driver out of line. Since the addition can now
fail, we can have IBSS peer structs the driver
rejected -- in that case we still talk to the
station but never tell the driver about it in
the control.sta pointer. If there will ever be
a driver that has a low limit on the number of
stations and that cannot talk to any stations
that are not known to it, we need to do come up
with a new strategy of handling larger IBSSs,
maybe quicker expiry or rejecting peers.

mac80211: fix deferred hardware scan requests
Reinette found the reason for the warnings that
happened occasionally when a hw-offloaded scan
finished; her description of the problem:
mac80211 will defer the handling of scan requests if it is
busy with management work at the time. The scan requests
are deferred and run after the work has completed. When
this occurs there are currently two problems.
* The scan request for hardware scan is not fully populated
with the band and channels to scan not initialized.
* When the scan is queued the state is not correctly updated
to reflect that a scan is in progress. The problem here is
that when the driver completes the scan and calls
ieee80211_scan_completed() a warning will be triggered
since mac80211 was not aware that a scan was in progress.
The reason is that the queued scan work will start
the hw scan right away when the hw_scan_req struct
has already been allocated. However, in the first
pass it will not have been filled, which happens
at the same time as setting the bits. To fix this,
simply move the allocation after the pending work
test as well, so that the first iteration of the
scan work will call __ieee80211_start_scan() even
in the hardware scan case.

b43: Fix throughput regression
Commit
c7ab5ef9bcd281135c21b4732c9be779585181be entitled "b43: implement
short slot and basic rate handling" reduced the transmit throughput for
my BCM4311 device from 18 Mb/s to 0.7 Mb/s. The basic rate handling
portion is OK, the problem is in the short slot handling.
Prior to this change, the short slot enable/disable routines were never
called. Experimentation showed that the critical part was changing the
value at offset 0x0010 in the shared memory. This is supposed to contain
the 802.11 Slot Time in usec, but if it is changed from its initial value
of zero, performance is destroyed. On the other hand, changing the value
in the MMIO register corresponding to the Interframe Slot Time increased
performance from 18 to 22 Mb/s. A BCM4306/3 also shows dramatic
improvement of the transmit rate from 5.3 to 19.0 Mb/s.
Other changes in the patch include removal of the magic number for the
MMIO register, and allowing the slot time to be set for any PHY operating
in the 2.4 GHz band. Previously, the routine was executed only for G PHYs.

ath9k: add support for 802.11n bonded out AR2427
Some single chip family devices are sold in the market with
802.11n bonded out, these have no hardware capability for
802.11n but ath9k can still support them. These are called
AR2427.

ath9k: fix access to freed data on unload
Calling ath_bus_cleanup() after ieee80211_free_hw() resulted in access
to common->bus_ops, which is already freed as part of the device data.
Remove the cleanup field in struct ath_bus_ops, as it was never used
properly. Remove ath_bus_cleanup(). Merge cleanup functions in place
of the ath_bus_cleanup() calls. Take care not to use any device data
after ieee80211_free_hw().

mac80211: fix sta lookup with AP VLAN interfaces and injected frames
When injecting frames, mac80211 currently looks for the first AP
interface that matches the source address of the injected frame.
This breaks when such a frame is directed at a STA that has been moved
to a VLAN. This patch fixes it by using sta_info_get_bss instead of
sta_info_get, which also finds stations belonging to a VLAN interface
of the same BSS as the AP interface.

mac80211: fix monitor mode tx radiotap header handling
When an injected frame gets buffered for a powersave STA or filtered
and retransmitted, mac80211 attempts to parse the radiotap header
again, which doesn't work because it's gone at that point.
This patch adds a new flag for checking the availability of a radiotap
header, so that it only attempts to parse it once, reusing the tx info
on the next call to ieee80211_tx().
This fixes severe issues with rekeying in AP mode.

mac80211: fix sta lookup for received action frames on an AP VLAN
When looking for a matching interface, __ieee80211_rx_handle_packet
loops over all active interfaces, looking for matching stations.
Because AP VLAN interfaces are not processed as part of this loop, it
needs to use sta_info_get_bss instead of sta_info_get in order to find
a STA that has been moved to a VLAN.
This fixes issues with aggregation setup/teardown.
