Small changes in signal level was not detected up by the
MOVING_AVERAGE() due to a rounding error, using 'int' type.
rt2x00lib_antenna_diversity_eval:
rssi: -62 -62 -62 -62 -62 -62 -62 -62 -62 -62 -62 -62 -62 -62 -62
rssi_avg: -57 -57 -57 -57 -57 -57 -57 -57 -57 -57 -57 -57 -57 -57 -57
The signal level reported back could be significantly (5dBm)
different from the actual value. A level +3dBm is the same as
double the AP output power.

Antanna quality statistics is not handled correctly, which leads to
software diversity being shutdown completly.
The main problem is that during antenna diversity statistics can
be reset resulting in loosing the signal strength just before
evaluation.
rssi history is not updated correctly leading to incorrect comparison
material for basing antenna switching on.

Some hardware require the ieee80211 header to be aligned to a

IEEE80211_CONF_CHANGE_RADIO_ENABLED
In the config() callback function the fields radio_enabled and
the change flag IEEE80211_CONF_CHANGE_RADIO_ENABLED have been
deprecated. This removes the usage of those fields by improving
antenna change detection in the antenna configuration function.

Change rt2x00_rf_read() and rt2x00_rf_write() to subtract 1 from the rf
register number. This is needed because the rf registers are enumerated
starting with one. The size of the rf register cache is just enough to
hold all registers, so writing to the highest register was corrupting
memory. Add a check to make sure that the rf register number is valid.

Unloading rt61pci can leave the device in such state that reloading
rt61pci would fail to reinitialize it. Bogus data would be read from
the EEPROM and the RF version won't be recognized.
It appears that unloading rt61pci with power saving enabled would have
such effect. To initialize the device properly, SOFT_RESET_CSR should
be set to the same value as rt61pci_config_ps() uses to wake up the
device.

The mac80211 workqueue exists to enable mac80211 and drivers
to queue their own work on a single threaded workqueue. mac80211
takes care to flush the workqueue during suspend but we never
really had requirements on drivers for how they should use
the workqueue in consideration for suspend.
We extend mac80211 to document how the mac80211 workqueue should
be used, how it should not be used and finally move raw access to
the workqueue to mac80211 only. Drivers and mac80211 use helpers
to queue work onto the mac80211 workqueue:
* ieee80211_queue_work()
* ieee80211_queue_delayed_work()
These helpers will now warn if mac80211 already completed its
suspend cycle and someone is trying to queue work. mac80211
flushes the mac80211 workqueue prior to suspend a few times,
but we haven't taken the care to ensure drivers won't add more
work after suspend. To help with this we add a warning when
someone tries to add work and mac80211 already completed the
suspend cycle.
Drivers should ensure they cancel any work or delayed work
in the mac80211 stop() callback.

When only rt2400pci or rt2500pci is compiled without any of the other
rt2x00 modules, then CONFIG_RT2X00_LIB_CRYPTO will not be enabled.
However rt2x00mac_set_tim() implemented within #ifdef CONFIG_RT2X00_LIB_CRYPTO
statements while the declaration is placed outside the definition. This results in linking
errors as reporte by Ken.
rt2x00_set_tim() has nothing to do with crypto, and thus should be moved outside
of the #ifdef statements.

rt2x00dev->default_ant should be initialized once by the driver,
and should not be changed afterwards. Because rt2x00lib_config_antenna()
was using a reference to the struct antenna_setup it actually had the oppurtunity
to change the default antenna setting and it actually did that during the validation.
Instead of passing a pointer to antenna_setup the entire structure should be copied.

Implement set_tim callback for all rt2x00 drivers, this makes the
device wake up powersaving stations properly while in AP mode.
The only way to update the beacon is by simply calling mac80211 and
requesting the new beacon. This means the set_tim() event is mostly the
same as a beacon_done() event which was already defined in rt2x00lib.

Remove the input_polldev from rt2x00 and replace it with

Within mac80211, we often need to copy the rx status into
skb->cb. This is wasteful, as drivers could be building it
in there to start with. This patch changes the API so that
drivers are expected to pass the RX status in skb->cb, now
accessible as IEEE80211_SKB_RXCB(skb). It also updates all
drivers to pass the rx status in there, but only by making
them memcpy() it into place before the call to the receive
function (ieee80211_rx(_irqsafe)). Each driver can now be
optimised on its own schedule.

In a scenario where there isn't any firmware available, we will have a
double kfree of rt2x00dev->spec.channels_info when ieee80211_register_hw
returns an error status inside rt2x00lib_probe_hw.
The problem is that if ieee80211_register_hw fails, we call
rt2x00lib_remove_hw twice:
* first inside rt2x00lib_probe_hw upon failure of ieee80211_register_hw
* error status is returned to rt2x00lib_probe_dev, which then sees it and
calls in this case rt2x00lib_remove_dev that will again run
rt2x00lib_remove_hw
Prevent this avoiding calling rt2x00lib_remove_hw inside
rt2x00lib_probe_hw
Problem was detected with CONFIG_DEBUG_PAGEALLOC=y, CONFIG_SLUB_DEBUG=y,
CONFIG_SLUB_DEBUG_ON=y, that dumps this with no firmware available:
