_UCODE_API_OK was a intermediate version between MIN and
MAX. If a user had a firmware below _OK but above _MIN, the
driver would work but the user would get a warning in the
kernel log telling him to update his firmware.
This is not needed since most users won't look for these
messages in the kernel log if their wifi is working.

If something goes wrong with the firmware and we never get a scan

situation, add a timeout and trigger an NMI if it expires before
receiving the notification., so we can clean things up.

We want to request an interrupt vector for RSS queue per CPU,
one vector for fallback queue, and one for non-rx interrupts.
Future patch will make sure that no RSS traffic is directed to
fallback queue.
This will enable us to enable fast path on traffic that otherwise
would have been received on the fallback queue.

Currently the code checks if hardware reported both L4 and L3
checksums as valid, and only then reports it as validated to
the stack.
However, IPv6 does not have checksum at all and the L3 checksum
valid bit is always off for IPv6 packets, with the result of the
stack re-validating L4 checksum.
Fix code to set CHECKSUM_UNNECESSARY also for IPv6 packets whose
TCP/UDP checksum was verified.

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

Due to hardware bug, upon any shadow free-queue register write
access, a legacy RBD shadow register must be written as well.
This is required in order to trigger a copy of the shadow registers
values after MAC exits sleep state.
Specifically, the driver has to write (any value) to the legacy RBD
register each time FRBDCB is accessed.

"DQA" is shorthand for "dynamic queue allocation". This
enables on-demand allocation of queues per RA/TID rather than
statically allocating per vif, thus allowing a potential
benefit of various factors.
Please refer to the DOC section this patch adds to sta.h to
see a more in-depth explanation of this feature.
There are many things to take into consideration when working
in DQA mode, and this patch is only one in a series. Note that
default operation mode is non-DQA mode, unless the FW
indicates that it supports DQA mode.
This patch enables support of DQA for a station connected to
an AP, and works in a non-aggregated mode.
When a frame for an unused RA/TID arrives at the driver, it
isn't TXed immediately, but deferred first until a suitable
queue is first allocated for it, and then TXed by a worker
that both allocates the queues and TXes deferred traffic.
When a STA is removed, its queues goes back into the queue
pools for reuse as needed.

"is_data_qos == true" is equivalent to "tid < IWL_MAX_TID_COUNT"
since tid is only assigned (and range-checked) in that case.
This removes a (harmless) smatch warning that occurs because it

TX CMD API has changed to support offload assist.
Currently we do not enable checksum yet, but must set the
padding indication, to avoid FW errors.
Set other amsdu flag as well.
The rest of the flags will be configured only if HW csum
is enabled and will be set in future patches.
This change is backward compatible.

We insert padding if the MAC header's size is not a multiple of 4
to ensure that the SNAP header is DWORD aligned. When we do so, we
let the firmware know by setting a bit in Tx command
(TX_CMD_FLG_MH_PAD) which will instruct the firmware to drop those
2 bytes before sending the frame.
However, this is not needed for AMSDU as the sub frame header (14B)
complements the MAC header (26B) so that the SNAP header is DWORD
aligned without adding any pad.
Until 9000, the firmware didn't check the TX_CMD_FLG_MH_PAD bit
but rather checked the length of the MAC header itself and
assumed the entity that enqueued the frame (driver or internal
firmware code) added the pad.
Since the driver inserted the pad even for AMSDU this logic applied.
Note that the padding is a DMA optimization but it's not strictly
needed, so we could pad even if it was not needed.
However, the CSUM hardware introduced for the 9000 devices requires
to not pad AMSDU as it is not needed, and will fail if such a pad
exists.
Due to older FW not checking the padding bit but checking the mac
header size itself - we cannot do this adjustments for older
generations.
Do not align the size if it is an AMSDU and HW checksum is enabled -
which will only happen on 9000 devices and on.

When entering suspend the driver calls iwl_disable_interrupts() and
then iwl_pcie_disable_ict().
On resume the driver calls only iwl_pcie_reset_ict() without calling
explicitly to iwl_enable_interrupts().
This mostly works since iwl_pcie_reset_ict is calling to
iwl_enable_interrupts, but it doesn't work when there is no ict_table
in MSIx mode.
The result is that driver tries to resume but fails since it doesn't
get the RX interrupt from FW indicating that d0i3 exit was completed.
Fix it by adding an explicit call to enable interrupts.

LQM stands for Link Quality Measurement. The firmware
will collect a defined set of statitics (see the
notification for details) that allow to know how busy
the medium is. The driver issues a request to the firmware
that includes the duration of the measurement (the firmware
needs to be on channel for that amount of time) and the
timeout (in case the firmware has a lot of offchannel
activities). If the timeout elapses, the firmware will
send partial results which are still valuable.
In case of disassociation / channel switch and alike, the
driver is in charge of stopping the measurements and the
firmware will reply with partial results.
The user space API for now is debugfs only and will be
implmemented in an upcoming patch.

Paging contains 3 sections in the fw. The first for the paging separator,
The second for the CSS block, the third with the paging data.
Currently if the driver finds the paging separator, and there is only
section left (CSS), once reading the CSS section, the driver will
attempt to read the paging data and will go out of the arrays bounds.

paging.

Currently the driver has 2 buffers for paging:
1. paging db - this contains all of the pages that were in the FW
image, that the driver stores for the FW. This is allocated for each
block separately (not contiguous).
2. download buffer - we need to provide this empty buffer for the
iwl_sdio_load_fw_chunk function to copy the requested pages to the shared
memory. This is one big buffer of contiguous memory whose size is the
size of all the blocks that the fw paging section can contain.
This download buffer size is too big, and causes the allocation to fail
sometimes. Since the driver allocates memory for each block separately,
it is not possible for the FW to request all of the pages in one request
(the FW gives an address and size, so blocks need to be contiguous for
this to happen), therefore the FW is limited to request only one block.
Decrease the size of the paging download buffer to be the size of a
paging block.

6) Add 802.1AE MACSEC support, from Sabrina Dubroca.
7) Avoid factorial complexity when taking down an inetdev interface
with lots of configured addresses. We were doing things like
traversing the entire address less for each address removed, and
flushing the entire netfilter conntrack table for every address as
well.
8) Add and use SKB bulk free infrastructure, from Jesper Brouer.
9) Allow offloading u32 classifiers to hardware, and implement for
ixgbe, from John Fastabend.
10) Allow configuring IRQ coalescing parameters on a per-queue basis,
from Kan Liang.
11) Extend ethtool so that larger link mode masks can be supported.
From David Decotigny.
12) Introduce devlink, which can be used to configure port link types
(ethernet vs Infiniband, etc.), port splitting, and switch device
level attributes as a whole. From Jiri Pirko.
13) Hardware offload support for flower classifiers, from Amir Vadai.
14) Add "Local Checksum Offload". Basically, for a tunneled packet
the checksum of the outer header is 'constant' (because with the
checksum field filled into the inner protocol header, the payload
of the outer frame checksums to 'zero'), and we can take advantage
of that in various ways. From Edward Cree"

Code that was added back in 2.6.38 has an obvious overflow
when accessing a static array, and at the time it was added
only a code comment was put in front of it as a reminder
to have it reviewed properly.
This has not happened, but gcc-6 now points to the specific
overflow:
drivers/net/wireless/ath/ath9k/eeprom.c: In function 'ath9k_hw_get_gain_boundaries_pdadcs':
drivers/net/wireless/ath/ath9k/eeprom.c:483:44: error: array subscript is above array bounds [-Werror=array-bounds]
maxPwrT4[i] = data_9287[idxL].pwrPdg[i][4];
~~~~~~~~~~~~~~~~~~~~~~~~~^~~
It turns out that the correct array length exists in the local
'intercepts' variable of this function, so we can just use that
instead of hardcoding '4', so this patch changes all three
instances to use that variable. The other two instances were
already correct, but it's more consistent this way.
