The calculated values for the ACK timeout and ACK
consume time are different then the values as
used by the Legacy drivers.
After testing from James Ledwith it appeared that
the calculated values caused a high amount of TX
failures, and the values from the Legacy drivers
were the most optimal to prevent TX failure due to
excessive retries.
The symptoms of this problem:
- Rate control module always falls back to 1Mbs
- Low throughput when bitrate was fixed
Possible side-effects (not confirmed but highly likely)
- Problems with DHCP
- Broken connections due to lack of probe response
This should fix at least:
Kernel bugzilla reports: [13362], [13009], [9273]
Fedora bugzilla reports: [443203]
but possible some additional bugs as well.

The old function rt2x00queue_payload_align() handled
both adding and removing L2 padding and some basic
frame alignment. The entire function was being abused
because it had multiple functions and the header length
argument was somtimes used to align the header instead
of the payload.
Additionally there was a bug when inserting L2 padding
that only the payload was aligned but not the header. This
happens when the header wasn't aligned properly by mac80211,
but rt2x00lib only moves the payload.
A secondary problem was that when removing L2 padding during
TXdone or RX the skb wasn't resized to the proper size.
Split the function into seperate functions each handling
its task as it should.

Over time, a whole bunch of drivers have come up
with their own scheme to delay the configure_filter
operation to a workqueue. To be able to simplify
things, allow configure_filter to sleep, and add
a new prepare_multicast callback that drivers that
need the multicast address list implement. This new
callback must be atomic, but most drivers either
don't care or just calculate a hash which can be
done atomically and then uploaded to the hardware
non-atomically.
A cursory look suggests that at76c50x-usb, ar9170,
mwl8k (which is actually very broken now), rt2x00,
wl1251, wl1271 and zd1211 should make use of this
new capability.

When beacon is being updated to refresh TIM (AP mode), beacon frames are
de-synchronizing (i.e. two neighbor beacon frames - before and after
update - are being transmitted with a wrong time interval).
That is because xxx_write_beacon should disable beacon generation only
while beacon data are being uploaded to the device, but it should not
disable the beacon clock.

The patch "Implement set_tim callback for all drivers" can cause kernel
oops in rt73usb_write_beacon. The oops is caused by one of the following
race conditions:
* In case of two near calls to set_tim: rt2x00lib_beacondone_iter is
cleaning the beacon skb, whereas rt73usb_write_beacon is still using it.
* In case of two near updates of beacon: first as the result of set_tim
and second as the result of a call from an application (e.g. hostapd).
This patch fixes the race condition by rearranging the update logic and
guarding rt2x00_intf->beacon->skb with a mutex.

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

same as a beacon_done() event which was already defined in rt2x00lib.
