If a MCU timeout occurs before a hw restart completes, another hw restart
is scheduled, and the station state gets corrupted.
To speed up dealing with that, do not issue any MCU commands after the first
timeout, and defer handling timeouts until the reset has completed.
Also ignore errors in MCU commands during start/config to avoid making user
space fail on this condition. If it happens, another restart is scheduled
quickly, and that usually recovers the hardware properly.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.
This issue was found with the help of Coccinelle.

caps_buf is always of size sizeof(*caps) because
sizeof(caps->auth_encr_pair) * 16 is always zero. Notice
that when using zero-length arrays, sizeof evaluates to zero[1].
So, the code introduced by
commit 0308383f9591 ("rndis_wlan: get max_num_pmkids from device")
is logically dead, hence is never executed and can be removed. As a
consequence, the rest of the related code can be refactored a bit.
Notice that this code has been out there since March 2010.

(GTK) keys
When plumbing rxiv for (GTK) keys, current code does not use seq/seq_len
when present nor set iv_initialized for iovar wsec_key. This could
result in missing broadcast traffic after GTK rekey. The fix is setting
iv_initialized and using seq/seq_len for iovar wsec_key.

The driver sends an action frame down and waits for dwell time to be
completed or aborted before sending out the next action frame.
Driver issues "scan abort" to cancel the current time slot, but this
doesn't have any effect because, we are not using scan engine for
sending action frame.
Fix is to use "actframe_abort" to cancels the current action frame.

In WLAN, priority among various access categories of traffic is
always set by the AP using WMM parameters and this may not always
follow the standard 802.1d priority.
In this change, priority is adjusted based on the AP WMM params
received as part of the Assoc Response and the same is later used
to map the priority of all incoming traffic.
In a specific scenario where EDCA parameters are configured to be same
for all ACs, use the default FW priority definition to avoid queuing
packets of all ACs to the same priority queue.
This change fixes the following 802.11 certification tests:
* 11n - 5.2.31 ACM Bit Conformance test
* 11n - 5.2.32 AC Parameter Modification test
* 11ac - 5.2.33 TXOP Limit test

Change it to a flexible-array member and move it last again to
make it work correctly, prevent the same thing from happening
again (all compilers warn about flexible-array members in the
middle of a struct) and get it to build without warnings.

Currently when the sending of any management pkt
via wmi command fails, the packet is being unmapped
freed in the error handling. But the idr entry added,
which is used to track these packet is not getting removed.
Hence, during unload, in wmi cleanup, all the entries
in IDR are removed and the corresponding buffer is
attempted to be freed. This can cause a situation where
one packet is attempted to be freed twice.
Fix this error by rmeoving the msdu from the idr
list when the sending of a management packet over
wmi fails.

The qmi infrastructure sends the client a del_server
event when the client releases its qmi handle. This
is not the msg indicating the actual qmi server exiting.
In such cases the del_server msg should not be processed,
since the wifi firmware does not reset its qmi state.
Hence skip the processing of del_server event when the
driver is unloading.

The driver is not handling monitor status descriptor whenever

There are several "flavors" of HW that have the same HW type, but
can be told apart after reading a certain perph register. This
is easy to do in runtime, but more complicated to do when looking
at the logs offline.
To make it easier to tell apart these "flavors" when looking at
the dumped dbg info, add these bits to the HW type, allowing
simple differentiation.

We don't really expect fragmented RBs, and don't seem to be seeing
them in practice since that would've caused a crash. Nevertheless,
we should be expecting the hardware to send them.
Parse the flag indicating a fragmented buffer, but then discard it
and any fragments thereof, at least for now. We need to do more
work in the higher layers to properly deal with this, since we may
not get "normal" firmware notifications that are fragmented, only
RX, and then we need to put it back together and add the necessary
API to report a chain of things to the higher layers, this doesn't
fit into the struct iwl_rx_cmd_buffer today.

When we have 256 block-ack support, we may need to be very fast
to provide a lot of frames to the hardware to transmit, but that
cannot be guaranteed. Use a longer queue size to have more time,
and the next possible queue size is 1024 since it must be a power
of two.

Since the recent patch in this area, we no longer allocate 64k
for a single queue, but only 1k, which still means a full page.
Use a DMA pool to reduce this further, since we will have a lot
of queues in a typical system that can share pages.

We currently attempt to allocate queues that are 512 entries long,
but that requires 32 KiB memory, which may not be available, at
least not contiguously. If we fail to allocate, attempt to use a
smaller queue all the way down to 16 entries (which fit into a
single page).

The hardware needs a byte-count table with the size of each frame
on the queue to build A-MPDUs, but:
* newer generation no longer have the duplicated space at the end,
they can deal with the wrap properly - and we don't even fill
the dup anyway
* we have a maximum queue size of 512 right now and don't use the
theoretical hardware maximum of 65536.
Together, this reduces the byte count table DMA allocation from
64KiB (65536*2 + 64*2 rounded up) to 1 KiB (though that might be
rounded up to a full 4 KiB page by the allocator, not sure it can
share the allocations.)
