Implement the get_antenna and set_antenna callback functions, which will
allow clients to control the antenna for all non-11n hardware (Antenna handling
in rt2800 is still a bit magical, so we can't use the set_antenna for those drivers
yet).
To best support the set_antenna callback some modifications are needed in the
diversity handling. We should never look at the default antenna settings to determine
if software diversity is enabled. Instead we should set the diversity flag when
possible, which will allow the link_tuner to automatically pick up the tuning.

All register reads/writes in rt2800usb were previously done with
rt2800_register_read/rt2800_register_write. These however indirectly
call rt2x00usb_register_read/rt2x00usb_register_write which adds an
additional overhead of at least one call and several move instructions
to each register access.
Replacing the calls to rt2800_register_read/rt2800_register_write with
direct calls to rt2x00usb_register_read/rt2x00usb_register_write gets
rid of quite a number of instructions in the drivers hotpaths (IRQ
handling and txdone handling).
For consistency replace all references to rt2800_register_read/write
with the rt2x00usb_register_read/write variants.

The two functions that are in rt2x00ht.c can be much better placed
closer to the places where the call-sites of these functions are (one
in rt2x00config.c and one in rt2x00queue.c) allowing us to make these
functions static.
Also, conditional compilations doesn't seem to be necessary anymore as
802.11n support is quite common nowadays.
This makes the code a bit easier readable and searchable.

Both USB and PCI drivers allow a system administrator to dynamically add
USB/PCI IDs to the device table that a driver supports via the
/sys/bus/{usb,pci,pci_express}/drivers/<driver-name>/new_id files.
However, for the rt2x00 drivers using this method currently crashes the
system with a NULL pointer failure.
This is due to the set-up of rt2x00 where the probe functions require a
rt2x00_ops structure in the driver_info field of the probed device. As
this field is empty for the dynamically added devices this fails for
these devices.
Fix this by introducing driver-specific probe wrappers that do nothing
but calling the bus-specific probe functions with the rt2x00_ops structure
as an argument, rather than depending on the driver_info field.

This allows the compiler to perform the necessary bitfield calculations
during compile time instead of run time and thus reduces the number of
instructions to run during each tasklet invocation. This should improve
performance in the RX hotpath.
This comes at the cost of a slight increase in the module size (for
example rt2800pci):

When powersaving is enabled, assocaition times are very high
(for WPA2 networks, the time can easily be around the 3 seconds).
This is caused, because the flushing of the queues takes
too much time. Without the flushing callback mac80211 assumes
a timeout of 100ms while scanning. Limit all flush waiting
loops to the same maximum.
We can apply this maximum by passing the drop status to the
driver, which makes sure the driver performs extra actions
during the waiting for the queue to become empty.
After these changes, association times fall within the
healthy range of ~0.6 seconds with powersaving enabled.
The difference between association time between powersaving
enabled and disabled is now only ~0.1 second (which can also
be due to the measuring method).

TX status is reported by the hardware when a packet has been
sent (or after TX failed after possible retries), which is some
time after the DMA completion. Since the rt2800usb hardware can
not signal interrupts we have to use a timer, otherwise the
TX status would only be read by the next packet's TX DMA
completion, or by the watchdog thread.

Add a timestamp to each queue entry which is updated whenever
the status of the entry changes, and remove the per-queue
timestamps. The previous check was incorrect and caused both
false positives and false negatives.
With the corrected check it comes apparent that the TX status
usually times out on rt2800usb unless there is sufficient traffic
(i.e. the next TX will complete the previous TX status).

Trying to fix the "TX status report missed" warnings
by reading the TX_STA_FIFO entries as quickly as possible.
The TX_STA_FIFO is too small in hardware, thus reading
it only from the workqueue is too slow and entries get lost.
Start an asynchronous read of the TX_STA_FIFO directly from
the TX URB completion callback (atomic context, thus it cannot
use the blocking rt2800_register_read()). If the async
read returns a valid FIFO entry, it is pushed into a larger
FIFO inside struct rt2x00_dev, until rt2800_txdone() picks
it up.
A .tx_dma_done callback is added to struct rt2x00lib_ops
to trigger the async read from the URB completion callback.

The number of flags defined for the rt2x00dev->flags field,
has been growing over the years. Currently we are approaching
the maximum number of bits which are available in the field.
A secondary problem, is that one part of the field are initialized only
during boot, because the driver requirements are initialized or device
requirements are loaded from the EEPROM. In both cases, the flags are
fixed and will not change during device operation. The other flags are
the device state, and will change frequently. So far this resulted in the fact
that for some flags, the atomic bit accessors are used, while for the others
the non-atomic variants are used.
By splitting the flags up into a "flags" and "cap_flags" we can put all flags
which are fixed inside "cap_flags". This field can then be read non-atomically.
In the "flags" field we keep the device state, which is going to be read atomically.
This adds more room for more flags in the future, and sanitizes the field access methods.

Since commit 0b7fde54f94979edc67bbf86b5adba702ebfefe8 "rt2x00: Protect
queue control with mutex" rt2x00 used rt2x00queue_pause_queue for
stopping a tx queue in mac80211. But in case of a failure in the tx
path rt2x00 still called ieee80211_stop_queue which stopped the queue
but prevented rt2x00queue_unpause_queue to wake the queue up again
resulting in a stuck tx queue.
Fix this by also using rt2x00queue_pause_queue in case of tx failures.

This patch adds WLAN LED support to the mac80211 rt2x00 driver for
Ralink SoC (rt305x) devices. The current WLAN LED drivers in
rt2800lib.c set the LED brightness via an MCU request, but do nothing
for SoC. This patch checks for SoC and sets the register to enable the
WLAN LED (instead of an MCU request). This enables the WLAN LED for
RT305x devices.

Some clients seem to rely upon the reception of BlockAckReqs to flush
their rx reorder buffer. In order to fix aggregation for these clients
rt2x00 should send a BlockAckReq if the transmission of an AMPDU
subframe fails.
Introduce a new flag TXDONE_AMPDU to indicate that this is an AMPDU
subframe and pass IEEE80211_TX_STAT_AMPDU_NO_BACK to mac80211 if an
AMPDU subframe failed during transmission.
This fixes aggregation problems with Intel 5100 Windows STAs (and maybe
others as well).

For STBC transmissions rt2x00 used the number of RxSTBC streams the
destination STA indicates in its HT capabilities as STBC value in
the TXWI.
However, the legacy drivers and our own comment in rt2800.h suggest
that the STBC field in the TXWI only allows a value of 0 or 1.
The values 2 and 3 are reserved (probably for future devices).
And indeed, STBC transmissions to STAs indicating more then 1
RxSTBC stream fail when the STBC field is set to something >1.
Fix this by only setting the STBC field to 1 when STBC should be
used.

rt2800 devices should adjust their tx power in accordance with the
eeproms temperature calibration values. Add a new driver callback
gain_calibration that is called every 4 seconds.
The rt2800 gain calibration routine simply runs the tx power
configuration that takes care of calculating the temperature
compensation delta.
We don't need to synchronize the calls to rt2800_config_txpower
as they should all happen from mac80211's single threaded workqueue.

Since commit d1c3a37ceeb1a5ea02991a0476355f1a1d3b3e83 ("mac80211:
clarify alignment docs, fix up alignment") removed the requirement
for a 4-byte aligned payload rt2x00queue_align_payload is obsolete
as mac80211 will align the payload when it passes the frame to the
net stack.
As a result we can remove the call to rt2x00queue_align_payload in the
rx path and since that's the last user we can remove
rt2x00queue_align_payload altogether.
One advantage is that we save some alignment operations for frames
that don't need to be aligned (for example beause they are not passed
to the net stack).

Instead of hardcoding the tx status fifo size as 512 calculate it based
on the number of tx queues and the number of entries per queue. Also
round the size up to a power of 2 as kfifo would otherwise round it
down.
On rt2800pci this will increase the kfifo size from 512 bytes to 1024
bytes which is then able to hold the tx status for all entries in all
tx queues.
Furthermore, if the number of tx queues or tx entries changes in the
future (use of the MGMT queue for example) the kfifo size doesn't need
to be updated.

In the spirit of optimizing the code to get the queue structure of TX queues,
also optimize the code to get beacon queues. We can simply use the bcn queue
field of the rt2x00_dev structure instead of using the rt2x00queue_get_queue
function.

The ATIM queue is considered to be a TX queue by the drivers that support
the queue. Therefore include support for the ATIM queue to the
rt2x00queue_get_tx_queue function so that the drivers that support the ATIM
queue can also use that function.
Add the support in such a way that drivers that do not support the ATIM
queue are not penalized in their efficiency.

Current code for the atim queue is strange, as it is considered in the
rt2x00_dev structure as a second beacon queue.
Normalize this by letting the atim queue have its own struct data_queue
pointer in the rt2x00_dev structure.
