cfg80211: Add nl80211 antenna configuration
Allow setting of TX and RX antennas configuration via nl80211.
The antenna configuration is defined as a bitmap of allowed antennas to use.
This API can be used to mask out antennas which are not attached or should not
be used for other reasons like regulatory concerns or special setups.
Separate bitmaps are used for RX and TX to allow configuring different antennas
for receiving and transmitting. Each bitmap is 32 bit long, each bit
representing one antenna, starting with antenna 1 at the first bit. If an
antenna bit is set, this means the driver is allowed to use this antenna for RX
or TX respectively; if the bit is not set the hardware is not allowed to use
this antenna.
Using bitmaps has the benefit of allowing for a flexible configuration
interface which can support many different configurations and which can be used
for 802.11n as well as non-802.11n devices. Instead of relying on some hardware
specific assumptions, drivers can use this information to know which antennas
are actually attached to the system and derive their capabilities based on
that.
802.11n devices should enable or disable chains, based on which antennas are
present (If all antennas belonging to a particular chain are disabled, the
entire chain should be disabled). HT capabilities (like STBC, TX Beamforming,
Antenna selection) should be calculated based on the available chains after
applying the antenna masks. Should a 802.11n device have diversity antennas
attached to one of their chains, diversity can be enabled or disabled based on
the antenna information.
Non-802.11n drivers can use the antenna masks to select RX and TX antennas and
to enable or disable antenna diversity.
While covering chainmasks for 802.11n and the standard "legacy" modes "fixed
antenna 1", "fixed antenna 2" and "diversity" this API also allows more rare,
but useful configurations as follows:
1) Send on antenna 1, receive on antenna 2 (or vice versa). This can be used to
have a low gain antenna for TX in order to keep within the regulatory
constraints and a high gain antenna for RX in order to receive weaker signals
("speak softly, but listen harder"). This can be useful for building long-shot
outdoor links. Another usage of this setup is having a low-noise pre-amplifier
on antenna 1 and a power amplifier on the other antenna. This way transmit
noise is mostly kept out of the low noise receive channel.
(This would be bitmaps: tx 1 rx 2).
2) Another similar setup is: Use RX diversity on both antennas, but always send
on antenna 1. Again that would allow us to benefit from a higher gain RX
antenna, while staying within the legal limits.
(This would be: tx 0 rx 3).
3) And finally there can be special experimental setups in research and
development even with pre 802.11n hardware where more than 2 antennas are
available. It's good to keep the API simple, yet flexible.

rt2x00: Fix hw crypto in AP mode for some devices
The BSSID register shouldn't be set in AP mode on some older devices (like
rt73usb) as it breaks hw crypto on these. However, rt2800 devices explicitly
need the BSSID register set to the same value as our own MAC address (only
in AP mode).
Hence, don't set the BSSID from rt2x00lib but move it down into rt2800 to
avoid problems on older devices.
This fixes a regression (at least for rt73usb) and avoids a new regression
for rt2800 devices in 2.6.36.

rt2x00: Fix crash on USB unplug
By not scheduling the TX/RX completion worker threads
when Radio is disabled, or hardware has been unplugged,
the queues cannot be completely cleaned.
This causes crashes when the hardware has been unplugged while
the radio is still enabled.

rt2x00: Fix MCU_SLEEP arguments
Legacy driver uses 0xff as the second argument for the MCU_SLEEP
command. It is still unknown what the values actually mean, but
this will at least keep the command in-sync with the original
driver.

rt2x00: Implement flush callback
Implement a basic flush callback function, which simply loops
over all TX queues and waits until all frames have been transmitted
and the status reports have been gathered.
At this moment we don't support dropping any frames during the
flush, but mac80211 will only send 'false' for this argument anyway,
so this is not important at this time.

rt2x00: Remove failsave from rt2x00usb_watchdog_tx_dma
When the TX status handler failed to clear the queue
in rt2x00usb_watchdog_tx_dma() we shouldn't use a failsave
to use the rt2x00usb txdone handler.
If a driver has overriden the txdone handler it must make
sure the txdone handler is capable of cleaning up the queue itself.

When rt2x00 is compiled with debugging but frame dumping is currently
not active we can avoid the call to do_gettimeofday. Furthermore,
frame dumping is not the default case, mark it as unlikely.

rt2x00: Reduce tx descriptor size
The tx descriptor values qid, cw_min, cw_max and aifs are directly
accessible through the tx entry struct. So there's no need to copy
them into the tx descriptor and passing them to the indiviual drivers.
Instead we can just get the correct value from the tx entry.

rt2x00: Sync Tx and RX ring sizes with legacy drivers
All rt2x00 devices used the same Tx and Rx ring size (24 entries) till
now. Newer devices (like rt2800) can however make use of a larger TX and
RX ring due to 11n capabilities (AMPDUs of size 64 for example).
Hence, bring rt2x00 in sync with the legacy drivers and use the same TX
and RX ring sizes. Also remove the global defines RX_ENTRIES, TX_ENTRIES,
BEACON_ENTRIES and ATIM_ENTRIES and use per driver values.
That is 24 entries for rt2400pci, 32 entries for rt2500pci, rt2500usb,
rt61pci and rt73usb and 128 (RX) and 64 (TX) for rt2800pci and rt2800usb.
