e6b0bd61a7 This pull contains a series of warning fixes from Mauro; once applied, the
number of warnings from the once-noisy docs build process is nearly zero.
 Getting to this point has required a lot of work; once there, hopefully we
 can keep things that way.
 
 I have packaged this as a separate pull because it does a fair amount of
 reaching outside of Documentation/.  The changes are all in comments and in
 code placement.  It's all been in linux-next since last week.

76c3bdd67d dt-bindings: staging: wfx: silabs,wfx yaml conversion
The device can be connected on SPI or on SDIO. The original file
described the two options separately. So, most of the file had to be
rewritten in order to match with the Yaml requirements.

Some device requirements are still written in the comments since they
cannot been expressed with the current scheme (e.g. reg must be set to 1
with SDIO, interrupt is mandatory with SPI, reset-gpio in SPI is
replaced by mmc-pwrseq in SDIO, etc...).

The examples provided have also been reworked in order to make
dt_binding_check happy.

Finally, also fix typo in the name of the file (siliabs instead of
silabs)

0d2dfdb885 staging: wfx: fix QoS priority for slow buses
The device is in charge of respecting the QoS constraints. The driver
have to ensure that all the queues contain data and the device choose
the right queue to send.

The things starts to be more difficult when the bandwidth of the bus is
lower than the bandwidth of the WiFi. The device quickly sends the
frames of the highest priority queue. Then, it starts to send frames
from a lower priority queue. Though, there are still some high priority
frames waiting in the driver.

To work around this problem, this patch add some priorities to each
queue. The weigh of the queue was (roughly) calculated experimentally by
checking the speed ratio of each queue when the bus does not limit the
traffic:
    - Be/Bk -> 20Mbps/10Mbps
    - Vi/Be -> 36Mbps/180Kbps
    - Vo/Be -> 35Mbps/600Kbps
    - Vi/Vo -> 24Mbps/12Mbps

So, if we fix the weigh of the Background to 1, the weight of Best
Effort should be 2. The weight of Video should be 116. However, since
there is only 32 queues, it make no sense to use a value greater than
64[1]. And finally, the weight of the Voice is set to 128.

[1] Because of this approximation, with very slow bus, we can still
observe frame starvation when we measure the speed ratio of Vi/Be. It is
around 35Mbps/1Mbps (instead of 36Mbps/180Kbps). However, it is still in
accepted error range.

4fd1241778 staging: wfx: fix BA sessions for older firmwares
Firmwares with API < 3.6 do not forward DELBA requests. Thus, when a
Block Ack session is restarted, the reordering buffer is not flushed and
the received sequence number is not contiguous. Therefore, mac80211
starts to wait some missing frames that it will never receive.

This patch disables the reordering buffer for old firmware. It is
harmless when the network is unencrypted. When the network is encrypted,
the non-contiguous frames will be thrown away by the TKIP/CCMP replay
protection. So, the user will observe some packet loss with UDP and
performance drop with TCP.

8d350c14ee staging: wfx: fix handling of MMIC error
As expected, when the device detect a MMIC error, it returns a specific
status. However, it also strip IV from the frame (don't ask me why).

So, with the current code, mac80211 detects a corrupted frame and it
drops it before it handle the MMIC error. The expected behavior would be
to detect MMIC error then to renegotiate the EAP session.

So, this patch correctly informs mac80211 that IV is not available. So,
mac80211 correctly takes into account the MMIC error.

3768c74b3a staging: wfx: drop async field from struct hif_cmd
The parameter "async" in wfx_cmd_send() allows to send command without
waiting for the reply. In this case, the mutex hif_cmd.lock is released
asynchronously in the context of the receiver workqueue.

However, "kbuild test robot" complains about this architecture[1] since
it is not able to follow the lock duration of hif_cmd.lock (and indeed,
the state of the driver if the hardware wouldn't reply is not well
defined).

Besides, this feature is not really necessary. It is only used by
hif_shutdown(). This function hijack the 'async' flag to run a command
that won't answer.

So, this patch removes the 'async' flag and introduces a 'no_reply' flag.
Thus, the mutex hif_cmd.lock is only acquired/released from
hif_cmd_send(). Therefore:
  - hif_shutdown() does not have to touch the private data of the struct
    hif_cmd
  - Kbuild test robot should be happy
  - the resulting code is simpler

hif_tx_mib.c contains functions that format data to be sent to the

This patch uniformize the things and choose to call all the data in
destination to the hardware 'arg' (note this choice is only dictated by
the number of lines to change in the code)

The Secure Link (slk) feature allows to encrypt (and authenticate) the
traffic between the host and the device. The official implementation of
this feature relies on mbedTLS. For that reason, this implementation is
not included in the current driver. To be included, the implementation
has to rely on kernel crypto API instead of mbedTLS.

So, for now, the driver contained stub functions waiting for the new
implementation based on kernel crypto API.

This new implementation represent a bunch of work and it is unlikely to
be done in near future.  Moreover, we strongly dislike to maintain
useless code. So, drop all the code related to secure link.

Whoever wants to implement secure link should revert this patch before
starting to work on it.
