All rt2x00 drivers except rt2800pci call ieee80211_tx_status() from

rt2x00lib_txdone(). For the rt2800pci special case a driver

RF5413 that seems to have a completely different bank 2. Also
since 2317 has the same rf-registers locations with 2425 and

set channel on PHY while PHY is running instead of doing a normal
full reset. To do this phy_init has to change to implement this
functionality.
* Clean up change_channel flag, what it really did was skip PCU
registers when setting initvals. This is done because on reset
PCU registers are not affected (except the registers we set
in pcu init and -due to hw problems- TSF). Use a new skip_pcu
flag that's not misleading instead. In the future we might use
that to also skip PCU reset and save us the TSF etc problems
(needs testing because standard practice is to reset everything).
* Use fast channel change only when setting channel, and set skip_pcu
to false only on init. When we reset the card due to DMA or PHY

This change moved the initialization of the AH_USE_EEPROM flag from ath9k_hw
to ath9k. This needs to be added to ath9k_htc as well

Under load, a large number of frames can produce decryption errors, even when

It seems that using ath9k_hw_stoppcurecv to stop rx dma is not enough.
When it's time to stop DMA, the PCU is still busy, so the rx enable
bit never clears.
Using ath9k_hw_abortpcurecv helps with getting rx stopped much faster,
with this change, I cannot reproduce the rx stop related WARN_ON anymore.

On the disassociation event from the mac80211, the wl12xx driver does not
clear the chipset configuration related to the AP - i.e. it does not perform
a DISCONNECT and then a JOIN with zero SSID and dummy BSSID. Also, it does not
unset the BSSID filter.
Often this is not a problem, as the above is performed upon entering idle
state. But if a scenario arises where a new association is attempted without
cycling through idle state, the new association will fail.
Fix this by resetting the firmware state on disassociation.

Since the pointers after the rates in the tx info cannot be used anymore
after frames have been queued, this area can be used to store information
that was previously stored in the ath_buf. With these changes, we can delay
the ath_buf assignment in the aggregation code until aggregates are formed.
That will not only make it possible to simplify DMA descriptor setup to
do less rewriting of uncached memory, but will also make it easier to
move aggregation out of the core of the ath9k tx path.

BCM4320a devices do not return bss for currently connected AP in bss-list,
althought this is required by NDIS specs. Missing bss leads to warning at

Workaround this by crafting bss manually with information we can read from
device. Workaround is only used when device bss-list does not return current
bss, and so is only used with BCM4320a devices and not newer BCM4320b ones.

The mwl8k can operate in AP or STA mode, depending on the
firmware image that is loaded. By default, STA firmware is
loaded. Allow the user to override this default mode at
module load time. This saves an unnecessary firmware reload
for users only interested in AP mode.
Also, the firmware image can be swapped to meet the user's
add_interface request. For example, suppose the STA
firmware is loaded, no STA interface has been added, and the
user adds an AP interface. In this case, the AP firmware
will be loaded to meet the request.

Certain firmware versions, particularly the 8388 found on the XO-1,
do not support the EHS_REMOVE_WAKEUP command that is used to disable
WOL. Sending this command to the card will return a failure that
would get propagated up the stack and cause suspend to fail.
Instead, fall back to an all-zero wakeup mask.

This hunk added by commit 66fceb69b7 seems erroneous. We don't want to
prevent suspend of the whole system if no wakeup params are set.
In the case of the usb8388 we do want to keep the card powered up even
if there are no wakeup params. This is because it will continue acting
as a mesh node.
If the mesh is disabled, it would indeed make more sense to power down
the card during suspend, as the equivalent hunk does for the SD interface.
But that's a separate task; for now just restore the previous behaviour.

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.
