b01147140a iwlwifi: mvm: allow firmware crashes to wake system for debug
When the D3 firmware crashes, it can be helpful for debugging to
resume the system to get the SRAM snapshot to see why it crashed.
Allow enabling this with a debugfs option.

a2d0909a68 iwlwifi: bump required firmware API version for 3160/7260
As the firmware API has changed significantly and we don't
have support code for the old APIs, bump the version to be
able to release the version 7 API firmware. Unfortunately
this means that the driver in 3.9 and 3.10 can't work, but
that's still better than crashing the device/driver there.

4f25bbdb16 iwlwifi: create opmode/device dependencies
The older devices (pre-7000/3000 series) all only work with the
DVM opmode due to firmware availability, while newer ones will
only work with the MVM opmode for the same reason.

When building a driver that only has one of MVM or DVM, there's
no reason to build the device support and have the PCIe IDs for
all devices since they can't be used anyway, so avoid that.

51cd53ad12 iwlwifi: reduce debug ifdefs using the optimiser
Instead of using #ifdef CONFIG_IWLWIFI_DEBUG, remove the
iwlwifi_mod_params.debug_level variable completely and
make iwl_have_debug_level() always return false in the
non-debug case. This way, the optimiser will elide all
code for it automatically without having to add #ifdefs.

01911dab97 iwlwifi: pcie: don't read INTA register in ICT IRQ handler
There's no reason to read the INTA register in the ICT IRQ
handler, this interrupt mechanism is designed to not have
to read as many registers as the regular one. Not reading
the INTA register gives a significant performance/CPU use
improvement.

Since we still want to get this info, fetch it only if
the ISR debug level is enabled.

10af87c3d9 rt2x00: rt2x00queue: initialize data_queue fields earlier
Support for rt2800 device is broken since my
'rt2x00: rt2x00dev: use rt2x00dev->tx->limit'
patch. The changelog of that commit says that the
TX data queue is initialized already when the
rt2x00lib_probe_hw() function is called.

However as Jakub noticed it, this statement is not
correct. The queue->limit field is initialized in
the rt2x00queue_alloc_entries routine and that is
not yet called when rt2x00lib_probe_hw() runs.
Because the value of tx->limit contains zero, the
driver tries to allocate a kernel fifo with zero
size and kfifo_alloc rejects that with -EINVAL.

  PCI: Enabling device 0000:01:00.0 (0000 -> 0002)
  ieee80211 phy1: rt2x00_set_rt: Info - RT chipset 3071, rev 021c detected
  ieee80211 phy1: rt2x00_set_rf: Info - RF chipset 0008 detected
  ieee80211 phy1: rt2x00lib_probe_dev: Error - Failed to initialize hw
  rt2800pci: probe of 0000:01:00.0 failed with error -22

Move the data_queue field initialization from
the rt2x00queue_alloc_entries routine into the
rt2x00queue_init function. The initialization
code is not strictly related to the allocation,
and the change ensures that the queue_data fields
can be used in the probe routines.

The patch also introduces a helper function in
order to be able to get the correct data_queue_desc
structure for a given queue. This helper is only
needed temporarily and it will be removed later.

The optional debugfs interface to the vendor's engineering tools wasn't

This patch checks both the length supplied as part of the data to ensure
it is sane, and also the amount of data compared to the remaining buffer
space.  If either is too large, fail immediately.

high. Change power management enablement. When unassociated in BPS and

decision. Rely on mac80211 decision if associated. Add power management

The AP mode needs to use the MCAST fifo for the MCAST

configured with the same parameters as the VOICE FIFO.

A separate SCD queue is mapped to this fifo - the cab_queue
(cab stands for Content After Beacon). This queue isn't
connected to any station, but rather to the MAC context.
This queue should (and is already) be set as the MCAST
queue - this is part of the of MAC context command.

8d683b7948 iwlwifi: mvm: Fix quota command settings

have a valid entry for each active binding (where 'active' in
this context means that the binding is known to the FW). In case
the binding should not get any quota, the 'quota' should be set
to zero.

Not setting an 0 quota for an active binding when all the MACs
in the binding are idle, i.e., not associated in case of managed
interface, will result in preventing the FW scheduler from entering
IDLE state and the FW from transitioning to low PS.
