* some more dynamic queue allocation work
* SAR BIOS implementation
* some work on debugging capabilities
* added support for GCMP encryption
* data path rework in preparation for new HW
* some cleanup to remove transport dependency on mac80211
* support for MSIx in preparation for new HW
* lots of work in preparation for HW support (9000 and a000 series)
mwifiex
* implement get_tx_power and get_antenna cfg80211 operation callbacks
wl18xx
* add support for 64bit clock
rtl8xxxu
* aggregation support (optional for now)
Also wireless-drivers is merged to fix some conflicts.

Some transports may sleep when writing to registers, which is done
when calling iwl_force_nmi(). So we can't call iwl_force_nmi() in a
timer context. To solve that, convert the scan timeout timer to a
delayed work.

Add the following to support beacon report radio measurement
with the measurement mode field set to passive or active:
1. Propagate the required scan duration to the device
2. Report the scan start time (in terms of TSF)
3. Report each BSS's detection time (also in terms of TSF)
TSF times refer to the BSS that the interface that requested the
scan is connected to.

The 16 seconds timeout we were using turned out to be too short.
Recalculations by system show that the total time in both bands should
be < 18.5 seconds, even in the slowest cases (e.g. DCM P2P with
DTIM=2). Rounding it up to 20 seconds for a bit more safety.

This enum is already perfectly aliased to enum nl80211_band, and
the only reason for it is that we get IEEE80211_NUM_BANDS out of
it. There's no really good reason to not declare the number of
bands in nl80211 though, so do that and remove the cfg80211 one.

If something goes wrong with the firmware and we never get a scan
complete notification, we stay stuck forever. In order to avoid this
situation, add a timeout and trigger an NMI if it expires before
receiving the notification., so we can clean things up.

The firmware doesn't send match found notifications when no matchsets
are passed. This makes sense because if there are no matchsets,
nothing can be matched. But the nl80211 API should report when there
are results available, even if no matchsets were passed.
To handle this, we can use the firmware's ITERATION_COMPLETE
reporting, which will send us notifications every time it completed a
scheduled scan iteration. Then we can set a flag when we received
beacons and use that to report that results are available.

These are a few fixes for the current cycle.
3 out of the 5 patches fix a bugzilla.
* fix a race that users reported when we try to load the firmware
and the hardware rfkill interrupt triggers at the same time.
* Luca fixes a very visible bug in scheduled scan: our firmware
doesn't support scheduled scan with no profile configured and
the supplicant sometimes requests such scheduled scans.
* build system fix
* firmware name update for 8265
* typo fix in return value

The firmware can perform a scheduled scan with not matchsets passed,
but it can't send notification that results were found. Since the
userspace then cannot know when we got new results and the firmware
wouldn't trigger a wake in case we are sleeping, it's better not to
allow scans without matchsets.

Currently when the driver is configured with wowlan parameters, and enters
D3 mode, the driver switches the FW image to D3, and when it exists
suspend, it reloads the D0 image.
If the firmware supports the consolidation of the D0 & D3 images there is
no need to load the D3 image on suspend, and no need to reload the D0
image on resume.
Do not switch images on suspend / resume, for firmwares that support
consolidated images.

FW adds 10 msec for every dwell time in low band, so we need
to set 10 msec less.
Don't use extended dwell time when fragmented scan is needed
because FW adds 3 msec per probe and it can easily exceed
max out of channel time.

When doing active scan on crowded channels we are likely to miss probe
responses due to collisions. To overcome this issue we use an extended
dwell time on channels 1, 6 and 11; this dwell time is set to 100.
In case of fragmented scan extended dwell time is the maximum out of
channel time - 44 msec. Fragmented active scan will be addressed later.
Extended dwell time isn't used in sched scan or p2p find.
