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 PCIe transport needs to store two pointers in each TX SKB, and
currently assumes mac80211's ieee80211_tx_info is present in the CB
to do that.
In order to remove that assumption, have the opmodes pass in the
offset to where the pointers can be stored in the CB and use the
offset in the PCIe code.
To make the disentanglement complete, remove mac80211.h includes
from everywhere in the generic iwlwifi code. This required adding
an include of cfg80211.h in one place.

The new hardware that supports multiple queue also
de-aggregates A-MSDUs. This means that we can advertise
the maximal size of A-MSDUs regardless of the receive
buffer's size.
In order to be able to forcefully use a lower A-MSDU size,
add a default value for the module parameter. Pre-9000
will have a default of 4K, and 9000 will have 12K.
Setting the amsdu_size module parameter to 4K will limit
the A-MSDU on 9000 as well.

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

Use alloc_ordered_workqueue() to allocate the workqueue instead of
create_singlethread_workqueue() since the latter is deprecated and is scheduled
for removal.
There are work items doing related operations that shouldn't be swapped when
queued in a certain order hence preserve the strict execution ordering of a
single threaded (ST) workqueue by switching to alloc_ordered_workqueue().
WQ_MEM_RECLAIM flag is not needed since the worker is not depended

Newer firmware versions put different data in the memory
which is read by the driver upon firmware crash. Just
change the variable names in the code and the name of the
data in the log that we print withouth any functional
change.
On older firmware, there will be a mismatch between the
names that are printed and the content itself, but that's
harmless.

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.

Rewrite abs() so that its return type does not depend on the
architecture and no unexpected type conversion happen inside of it. The
only conversion is from unsigned to signed type. char is left as a
return type but treated as a signed type regradless of it's actual
signedness.
With the old version, int arguments were promoted to long and depending
on architecture a long argument might result in s64 or long return type
(which may or may not be the same).
This came after some back and forth with Nicolas. The current macro has
different return type (for the same input type) depending on
architecture which might be midly iritating.
An alternative version would promote to int like so:
#define abs(x) __abs_choose_expr(x, long long, \
__abs_choose_expr(x, long, \
__builtin_choose_expr( \
sizeof(x) <= sizeof(int), \
({ int __x = (x); __x<0?-__x:__x; }), \
((void)0))))
I have no preference but imagine Linus might. :] Nicolas argument against
is that promoting to int causes iconsistent behaviour:
int main(void) {
unsigned short a = 0, b = 1, c = a - b;
unsigned short d = abs(a - b);
unsigned short e = abs(c);
printf("%u %u\n", d, e); // prints: 1 65535
}
Then again, no sane person expects consistent behaviour from C integer
arithmetic. ;)
Note:
__builtin_types_compatible_p(unsigned char, char) is always false, and
__builtin_types_compatible_p(signed char, char) is also always false.

My commit below introduced a mutex in the transport to
prevent concurrent operations. To do so, it added a flag
(is_down) to make sure the transport is in the right state.
This uncoverred an bug that didn't cause any harm until
now: iwldvm calls stop_device and then starts the firmware
without calling start_hw in between. While this flow is
fine from the device configuration point of view (register,
etc...), it is now forbidden by the new is_down flag.
This led to this error to appear:
iwlwifi 0000:05:00.0: Can't start_fw since the HW hasn't been started
and the suspend would fail.
