When an interface is configured in the AP mode, the mac80211
implementation doesn't inform the driver to receive PS Poll frames.
It leads to inability to communicate with power-saving stations
reliably.
The FIF_CONTROL flag isn't passed by mac80211 to
ieee80211_ops.configure_filter when an interface is in the AP mode.
And it's ok, because we don't want to receive ACK frames and other
control ones, but only PS Poll ones.
This patch introduces the FIF_PSPOLL filter flag in addition to
FIF_CONTROL, which means for the driver "pass PS Poll frames".
This flag is passed to the driver:
A) When an interface is configured in the AP mode.
B) In all cases, when the FIF_CONTROL flag was passed earlier (in
addition to it).

If hw initialization fails (ath9k_hw_init()) on ath_init_softc()
we bail out and call ath9k_hw_detach(). The call ath9k_hw_detach()
is conditional though as ath9k_hw_init() could itself have called
ath9k_hw_detach(). Just describing this is itself a brain twister.
Avoid this nonsense by removing ath9k_hw_detach() from ath9k_hw_init().
Upon hw initialization failure we expect the callers to take care of
the cleanup.

The SME state machine in cfg80211 uses the SSID stored
in struct wireless_dev internally, but fails to clear
it in multiple places (when giving up on a connection
attempt and when disconnecting). This doesn't matter to
the SME state machine, but does matter for IBSS. Thus,
in those cases, clear the SSID to avoid messing up the
IBSS state machine.

Unloading rt61pci can leave the device in such state that reloading
rt61pci would fail to reinitialize it. Bogus data would be read from
the EEPROM and the RF version won't be recognized.
It appears that unloading rt61pci with power saving enabled would have
such effect. To initialize the device properly, SOFT_RESET_CSR should
be set to the same value as rt61pci_config_ps() uses to wake up the
device.

As shown in http://thread.gmane.org/gmane.linux.kernel.wireless.general/36497,
mac80211 has a bug that allows a call to the TX routine after the queues have
been stopped. This situation will only occur under extreme stress. Although
b43legacy does not crash when this condition occurs, it does generate a WARN_ON
and also logs a queue overrun message. This patch recognizes b43legacy is not
at fault and logs a message only when the most verbose debugging mode is
enabled. In the unlikely event that the queue is not stopped when the DMA
queue becomes full, then a warning is issued.
This patch is based on the one used by b43.

For 6x00 2x2 NIC, two types of Power Amplifier are available.
In order for uCode to apply correct tx power,
driver needs to program the CSR_GP_DRIVER_REG register and
let uCode know the type of PA.
If driver do not program CSR_GP_DRIVER_REG register (default to 0),
then it is uCode's decision for tx power

The SPI driver writes to the bus mode register and performs a sanity
check by reading back what we wrote, however only the lower four bits of
that register are defined. In some cases, the device side seems to set
the higher bits, causing us to fail the sanity check unnecessarily.
Check only the lower four bits instead.

problem.
