iwlagn: update write pointers for all tx queues after wakeup
Wakeup interrupt has been updating write pointers (indexes, actually) only
for tx queues 0-5. This is adequate just for 3945, but inadequate for other
devices, all of which have more tx queues. Now updating all tx/command queues,
so device can be aware of all new tx and host commands enqueued while
device was asleep.
This can potentially improve data traffic bandwidth and/or latency.

iwlwifi: remove power-wasting calls to apm_ops.init()
To save power, don't run apm_ops.init() until needed at "up" time.
EEPROM (5000 and earlier devices) may be read without running apm_ops.init(),
but OTP reads (6000 and newer devices) require a powered-up chip.
Therefore, remove apm_ops.init() from the general path in XXXX_pci_probe(),
and call it only if device uses OTP. Once done with OTP read, call
apm_ops.stop() to reset chip and save power until "up" time comes around.

libertas: remove internal buffers from GSPI driver
This patch removes the internal command and data buffers that the GSPI driver
maintained and instead relies on the Libertas core to synchronize access
to the command and data ports as with the other interface drivers. This
cleanup reduces the GSPI driver's memory footprint and should improve
performance by removing the need to copy to these internal buffers.
This also simplifies the bottom half of the interrupt handler.
This is an incremental cleanup: after removing the redundant buffers, we
can further improve the driver to use a threaded IRQ handler instead of
maintaining its own thread. However I would like a few folks to test
the buffer removal first and make sure that I'm not introducing
regressions.
Tested on Blackfin BF527 with DMA disabled due to an issue with the SPI
host controller driver in the current bleeding-edge Blackfin kernel. I
would appreciate it if someone with working DMA could test this patch

mac80211: fix radiotap header generation
In
commit
601ae7f25aea58f208a7f640f6174aac0652403a
Author: Bruno Randolf <br1@einfach.org>

mac80211: make rx radiotap header more flexible
code was added that tried to align the radiotap header
position in memory based on the radiotap header length.
Quite obviously, that is completely useless.
Instead of trying to do that, use unaligned accesses
to generate the radiotap header. To properly do that,
we also need to mark struct ieee80211_radiotap_header
packed, but that is fine since it's already packed
(and it should be marked packed anyway since its a
wire format).

mac80211: split hardware scan by band
There's currently a very odd bug in mac80211 -- a
hardware scan that is done while the hardware is
really operating on 2.4 GHz will include CCK rates
in the probe request frame, even on 5 GHz (if the
driver uses the mac80211 IEs). Vice versa, if the
hardware is operating on 5 GHz the 2.4 GHz probe
requests will not include CCK rates even though
they should.
Fix this by splitting up cfg80211 scan requests by
band -- recalculating the IEs every time -- and
requesting only per-band scans from the driver.
Apparently this bug hasn't been a problem yet, but
it is imaginable that some older access points get
confused if confronted with such behaviour.

mac80211: fix dynamic power save for devices with nullfunc support in hw
In TX path it was assumed that dynamic power save works only if
IEEE80211_HW_PS_NULLFUNC_STACK is set. But is not the case, there are
devices which have nullfunc support in hardware but need mac80211
to handle dynamic power save timers, TI's wl1251 is one of them.
The fix is to not check for IEEE80211_HW_PS_NULLFUNC_STACK in

IEEE80211_HW_SUPPORTS_DYNAMIC_PS flags and act accordingly.

Then also make mac80211 use debugfs_remove_recursive()

netdev: usb: dm9601.c can drive a device not supported yet, add support for it
I found that the current version of drivers/net/usb/dm9601.c can be used to
successfully drive a low-power, low-cost network adapter with USB ID
0a46:9000, based on a DM9000E chipset. As no device with this ID is yet
present in the kernel, I have created a patch that adds support for the device
to the dm9601 driver.
Created and tested against linux-2.6.32-rc5.

The mailbox command process would only process a maximum of 5 unrelated
firmware events while waiting for it's command completion status.
It should process an unlimited number of events while waiting for a maximum of 5 seconds.
