* GP (general purpose) CONTROL REGISTER
* Bit fields:
* 27: HW_RF_KILL_SW
* Indicates state of (platform's) hardware RF-Kill switch
* 26-24: POWER_SAVE_TYPE
* Indicates current power-saving mode:
* 000 -- No power saving
* 001 -- MAC power-down
* 010 -- PHY (radio) power-down
* 011 -- Error
* 9-6: SYS_CONFIG
* Indicates current system configuration, reflecting pins on chip
* as forced high/low by device circuit board.
* 4: GOING_TO_SLEEP
* Indicates MAC is entering a power-saving sleep power-down.
* Not a good time to access device-internal resources.
* 3: MAC_ACCESS_REQ
* Host sets this to request and maintain MAC wakeup, to allow host
* access to device-internal resources. Host must wait for
* MAC_CLOCK_READY (and !GOING_TO_SLEEP) before accessing non-CSR
* device registers.
* 2: INIT_DONE
* Host sets this to put device into fully operational D0 power mode.
* Host resets this after SW_RESET to put device into low power mode.
* 0: MAC_CLOCK_READY
* Indicates MAC (ucode processor, etc.) is powered up and can run.
* Internal resources are accessible.
* NOTE: This does not indicate that the processor is actually running.
* NOTE: This does not indicate that 4965 or 3945 has completed
* init or post-power-down restore of internal SRAM memory.
* Use CSR_UCODE_DRV_GP1_BIT_MAC_SLEEP as indication that
* SRAM is restored and uCode is in normal operation mode.
* Later devices (5xxx/6xxx/1xxx) use non-volatile SRAM, and
* do not need to save/restore it.
* NOTE: After device reset, this bit remains "0" until host sets
* INIT_DONE

* The problem here is that when we get here, the driver will

* using info->driver_data or info->rate_driver_data. Thus,
* when passing out the frame to the driver again, we would be
* passing completely bogus data since the driver would then
* expect a properly filled info->control. In mac80211 itself
* the same problem occurs, since we need info->control.vif
* internally.
*
* To fix this, we should send the frame through TX processing
* again. However, it's not that simple, since the frame will
* have been software-encrypted (if applicable) already, and
* encrypting it again doesn't do much good. So to properly do
* that, we not only have to skip the actual 'raw' encryption
* (key selection etc. still has to be done!) but also the
* sequence number assignment since that impacts the crypto
* encapsulation, of course.
*
* Hence, for now, fix the bug by just dropping the frame.

* (3) hardware/firmware processes TX fifo and suppresses a frame
* (4) we get TX status before having processed the frame and
* knowing that the STA has gone to sleep.
*
* This is actually quite unlikely even when both those events are
* processed from interrupts coming in quickly after one another or
* even at the same time because we queue both TX status events and
* RX frames to be processed by a tasklet and process them in the
* same order that they were received or TX status last. Hence, there
* is no race as long as the frame RX is processed before the next TX
* status, which drivers can ensure, see below.
*
* Note that this can only happen if the hardware or firmware can
* actually add STAs to the filter list, if this is done by the
* driver in response to set_tim() (which will only reduce the race
* this whole filtering tries to solve, not completely solve it)
* this situation cannot happen.
*
* To completely solve this race drivers need to make sure that they
* (a) don't mix the irq-safe/not irq-safe TX status/RX processing
* functions and
* (b) always process RX events before TX status events if ordering
* can be unknown, for example with different interrupt status
