If the AP thinks we are in power save state eventhough we are not truly
in that state, it sets the TIM bit and does not send a data frame unless
we send a null data frame to correct the state in the AP.
This might happen if the null data frame for wake up is lost in the air
after we disable power save.

There are number of small details about the keycache operations that
are very easy to miss (and forget), so better include detailed
comments in ath9k_hw_set_keycache_entry() to avoid having to figure
out this every time when having to touch this area.

There is no need to parse the AP's HT capabilities if
the STA uses TKIP/WEP cipher. This allows the rate control
module to choose the correct(legacy) rate table.

Software antenna tuning is broken because of an function
ordering problem during rt2x00link_tuner().
rt2x00link_precalculate_signal()
rt2x00leds_led_quality()
rt2x00lib_antenna_diversity()
rt2x00link_precalculate_signal() will reset the quality TX/RX counters,
however rt2x00lib_antenna_diversity() requires the RX counter to
see what RSSI value must be used for a particular antenna.
We can't change the ordering since rt2x00lib_antenna_diversity() might
reset other statistics which are needed by the function called earlier.
Move the reset of the quality TX/RX counters into a seperate function
and move the call to after rt2x00lib_antenna_diversity().

3945 can use iwl_activate_qos instead of iwl3945_activate_qos.

This adds SSB functionality to register a fallback SPROM image from the
architecture setup code.
Weird architectures exist that have half-assed SSB devices without SPROM attached to
their PCI busses. The architecture can register a fallback SPROM image that is
used if no SPROM is found on the SSB device.

Currently, the driver is unconditionally notified of beacon
interval. This is a problem in AP mode, because the driver has
to know that the beacon interval has actualy changed to recalculate
TBTT and reset the HW TSF. Fix this to make mac80211 notify the driver
only when the beacon interval has been reconfigured to a new value.

Incorrect Michael MIC key (RX, should have been TX) was set for the
group key in AP mode. This resulted in all broadcast frames triggering
Michael MIC errors and eventual TKIP countermeasures. The change here
sets the correct Michael MIC key based on whether the local end is the
authenticator (well, AP for now).

nohwcrypt=1 module parameter can now be used to disable hardware
crypto in ath9k. While the hardware acceleration handles most cases,
it may be useful to be able to force mac80211 software implementation
to be used for some tests, e.g., with virtual interface combinations
that may not yet be supported in the key cache configuration. In
addition, this allows management frame protection to be tested with
older hardware revisions.

As analyzed by Patrick McHardy, vlan needs to reset it's
netdev_ops pointer in it's ->init() function but this
leaves the compat method pointers stale.
Add a netdev_resync_ops() and call it from the vlan code.
Any other driver which changes ->netdev_ops after register_netdevice()
will need to call this new function after doing so too.
With help from Patrick McHardy.

A commit c1b56878fb68e9c14070939ea4537ad4db79ffae "tc: policing requires
a rate estimator" introduced a test which invalidates previously working
configs, based on examples from iproute2: doc/actions/actions-general.
This is too rigorous: a rate estimator is needed only when police's
"avrate" option is used.

Commit 6833c043f9fc03696fde623914c4a0277df2a0bc introduced the phy
auto-powerdown capability. While the APD feature only works for 5761
and 5784 asic revisions, the (harmless portion of the) code was applied
to all 5705 and newer devices. However, the 5906 phy departs from the
usual design. This commit was interfering with the 5906's ability to
negotiate link against some switches. This patch corrects the problem.

Currently it is possible to do just about everything with the arp table
from user space except treat an entry like you are using it. To that end
implement and a flag NTF_USE that when set in a netwlink update request
treats the neighbour table entry like the kernel does on the output path.
This allows user space applications to share the kernel's arp cache.
