is a code section in rt2x00lib_config_antenna (). The effect of that code

iwlagn: open/close envlope to force move BT state machine
In uCode, BT state machine need to receive open envlope
command before perform calibration; followed by close envlope
command to move to next stage.
Since Linux has two separated uCode, one for init and the second
one for runtime; we use open envlope commands for init uCode to
indicate we are ready to perform calibration operation.
But for runtime uCode, we are not doing any init calibration,
so we issue open/close envlope commands to force uCode move to
"BT COEX ON" state.

rt2x00: Cleanup rt2x00usb_watchdog_reset_tx
rt2x00usb_watchdog_reset_tx performs the same task
as rt2x00usb_kill_tx_queue, with the only difference
is that it waits for all entries to be returned to
the driver and for all frames the status has been
reported to mac80211.
We can easily split this task by calling rt2x00usb_kill_tx_queue,
sleep for a short period and invoke the TX status reporting
function. By adding the sleep() to the kill_entry we make sure
that even during shutdown we guarentee the entry has been killed when
the function returns. To make this work correctly the interrupt
handlers have to be updated to prevent checking for the RADIO_ENABLED
flag too early which prevents the ownership of the entry to be reset.
Additionally a check for the DEVICE_PRESENT flag is not required but
is nice to prevent race conditions when the device was unplugged.
Additionally rather then calling rt2x00usb_work_txdone() for
status reporting we let the driver perform the TX status reporting
first. If this is not sufficient then rt2x00usb_work_txdone() will
still be used to cleanup the mess.

rt2x00: Split watchdog check into a DMA and STATUS timeout
The watchdog for rt2800usb triggers frequently causing all URB's
to be canceled often enough to interrupt the normal TX flow.
More research indicated that not the URB upload to the USB host
were hanging, but instead the TX status reports.
To correctly detect what is going on, we introduce Q_INDEX_DMA_DONE
which is an index counter between Q_INDEX_DONE and Q_INDEX and indicates
if the frame has been transfered to the device.
This also requires the rt2x00queue timeout functions to be updated
to differentiate between a DMA timeout (time between Q_INDEX and
Q_INDEX_DMA_DONE timeout) and a STATUS timeout (time between
Q_INDEX_DMA_DONE and Q_INDEX_DONE timeout)

Somebody noticed this problem, and I outlined

The problem, as I understand it, is that when
we go offchannel while the driver has a queue
stopped, the driver will likely start draining
the queue and then enable it while offchannel.
This in turn will enable the interface queue,
and that leads to transmitting data frames on
the wrong channel.
Fix this by keeping track of offchannel status
per interface, and not enabling the interface
queues on interfaces that are offchannel when
the driver enables a queue.

Newer AGN microcode requires know the beacon
before starting the AP so that it can start
beaconing right away. Implement that.

iwlagn: send RXON timing before associating
The PAN functionality requires us to send the
timing including a valid DTIM period to the
microcode before associating, so request this
data from mac80211 and send it to the device.

iwlagn: queue frames according to context
Frames for different contexts need to be put
on different queues, and multicast after DTIM
frames have a special queue yet which also
depends on the context, so put all this into
the context.

iwlagn: remove iw_mode check for beacon
Since we have the beacon context now, we no
longer need to rely on iw_mode but can check
the beacon context interface's type. However,
that check must be in the work item instead
due to locking constraints (mutex must be
held when dereferencing beacon_ctx pointer).

Detect whether or not the ucode is PAN
capable and adjust the valid contexts
accordingly. To be able to do this, add
the PAN context to the array as well.
