'chan_stats' is (re)allocated in _mwifiex_fw_dpc() ->
mwifiex_init_channel_scan_gap(), which is called whenever the device is
initialized -- at probe or at reset.
But we only free it in we completely unregister the adapter, meaning we
leak a copy of it during every reset.
Let's free it in the shutdown / removal paths instead (and in the
error-handling path), to avoid the leak.
Ideally, we can eventually unify much of mwifiex_shutdown_sw() and
mwifiex_remove_card() (way too much copy-and-paste) to reduce the burden
on bugfixes like this. But that's work for tomorrow.

When we shut down the device (i.e., during 'reset'), we cancel any
outstanding work, but we don't clear any work-related flags. This can
cause problems if, e.g., we begin to queue a new firmware dump or card
reset while the other one is in progress. That might leave work_flags
with a stale value, and we might begin one of these *after* we've
completely reset the device. That doesn't make sense, because all
firmware context will have been lost by then.
This fixes some forms of cascading failures, where I:
(a) force a firmware dump (cat /sys/kernel/debug/mwifiex/mlan0/device_dump)
(b) run a Wifi scan in parallel (iw mlan0 scan)
(c) the scan times out due to (a) hogging the interface
(d) the command timeout triggers another firmware dump and a reset [*]
(e) the 2nd firmware dump flag persists across the reset
(f) as soon as the interface comes back up, we trigger the pending
firmware dump
(g) subsequent commands time out again, while we are processing the
firmware dump; return to (d)
[*] Note that automatic card_reset() support is not yet implemented for
the mwifiex PCIe driver, so we won't hit *exactly* this behavior yet.
But we can see similarly-confusing behaviors today.

If we reset because of a command timeout, we should reset this flag.
Otherwise, we might erroneously think the next command after reset is
timing out, and trigger another reset.
The above behavior effectively neuters the automatic card_reset()
behavior, as it means we will never recover from a command timeout
properly (and in fact, we might enter an infinite loop:
timeout -> reset -> (fake) timeout -> reset -> ...
This fixes a bug introduced with introduction of PCIe function level
reset support, but it was carried into the SDIO driver when it was
converted to use the same codepaths. And this is currently mostly a
problem only in the SDIO driver, because it's the only one with
automatic card_reset() support (e.g., on command timeout). But it will
be a problem for PCIe too, as I'm working on supporting automatic
card_reset() for PCIe.

Command buffers (skb's) are allocated by the main driver, and freed upon
the last use. That last use is often in mwifiex_free_cmd_buffer(). In
the meantime, if the command buffer gets used by the PCI driver, we map
it as DMA-able, and store the mapping information in the 'cb' memory.
However, if a command was in-flight when resetting the device (and
therefore was still mapped), we don't get a chance to unmap this memory
until after the core has cleaned up its command handling.
Let's keep a refcount within the PCI driver, so we ensure the memory
only gets freed after we've finished unmapping it.
Noticed by KASAN when forcing a reset via:
echo 1 > /sys/bus/pci/.../reset
The same code path can presumably be exercised in remove() and
shutdown().

nl80211 provides the NL80211_SCAN_FLAG_RANDOM_ADDR for every scan
request that should be randomized; the absence of such a flag means we
should not randomize. However, mwifiex was stashing the latest
randomization request and *always* using it for future scans, even those
that didn't set the flag.
Let's zero out the randomization info whenever we get a scan request
without NL80211_SCAN_FLAG_RANDOM_ADDR. I'd prefer to remove
priv->random_mac entirely (and plumb the randomization MAC properly
through the call sequence), but the spaghetti is a little difficult to

The notification infrastructure (iwl_notification_wait_*
functions) allows to wait until a list of notifications
will come up from the firmware and to run a special handler
(notif_wait handler) when those are received.
The operation mode notifies the notification infrastructure
about any Rx being received by the mean of
iwl_notification_wait_notify() which will do two things:
1) call the notif_wait handler
2) wakeup the thread that was waiting for the notification
Typically, only after those two steps happened, the
operation mode will run its own handler for the notification
that was received from the firmware. This means that the
thread that was waiting for that notification can be
running before the operation mode's handler was called.
When the operation mode's handler is ASYNC, things get even
worse since the thread that was waiting for the
notification isn't even guaranteed that the ASYNC callback
was added to async_handlers_list before it starts to run.
This means that even calling
iwl_mvm_wait_for_async_handlers() can't guarantee that
absolutely everything related to that notification has run.
The following can happen:
Thread sending the command Operation mode's Rx path
-------------------------- ------------------------
iwl_init_notification_wait()
iwl_mvm_send_cmd()
iwl_mvm_rx_common()
iwl_notification_wait_notify()
iwl_mvm_wait_for_async_handlers()
// Possibly free some data
// structure
list_add_tail(async_handlers_list);
schedule_work(async_handlers_wk);
// Access the freed structure
Split the 'run notif_wait's handler' and the 'wake up the
thread' parts to fix this. This allows the operation mode
to do the following:
Thread sending the command Operation mode's Rx path
-------------------------- ------------------------
iwl_init_notification_wait()
iwl_mvm_send_cmd()
iwl_mvm_rx_common()
iwl_notification_wait()
// Will run the notif_wait's handler
list_add_tail(async_handlers_list);
schedule_work(async_handlers_wk);
iwl_notification_notify()
iwl_mvm_wait_for_async_handlers()
This way, the waiter is guaranteed that all the handlers
have been run (if SYNC), or at least enqueued (if ASYNC)
by the time it wakes up.

New transport will be used only by op modes that supports
buffer station offload - hence those will never be called.
Clean it up.

In a000 devices we have 16 bytes for the TFD index and 16 for the
queue, in order to support 512 queues.

Code is basically the same, with a cleanups of old narrow host
command, ampg workarounds, some cosmetic stuff, and usage of
TFH functions when accessing TFD queues.
This enables also the cleanup of iwl_pcie_tfd_set_tb() since
now it won't be called anywhere in the a000 data path

By moving all the code that depends on the new API
we avoid unnecessary indentation in the code.

Newer firmware versions will be able to handle all the
WMM-PS flows internally when we act as a GO. The firwmare
relies on the fact that the drivers puts frames for
different peers in different queues (DQA) to achieve this.
The driver will not be aware of the power state of the peers
anymore.
Tell the firmware about the WMM-PS parameters of earch peer
that connects to us so that it can know what are the
trigger-enabled ACs, the delivery-enableds ACs and the
Service Period length.
This API change is backward compatible since older firmware
versions will simply ignore the newly added values.
Since we don't support ieee80211 TSPECs for now, just copy
the trigger-enabled ACs to the delivery enabled ones.

There are several occasions where a scan of the same type is requested
concurrently, so logging every time this happens is just noisy and
unnecessary. Remove the logging for these cases.
