staging: wfx: fix coherency of hif_scan() prototype

2020-06-16T19:22:51+00:00

The function hif_scan() return the timeout for the completion of the
scan request. It is the only function from hif_tx.c that return another
thing than just an error code. This behavior is not coherent with the
rest of file. Worse, if value returned is positive, the caller can't
make say if it is a timeout or the value returned by the hardware.

Uniformize API with other HIF functions, only return the error code and
pass timeout with parameters.

staging: wfx: drop useless loop

2020-06-16T19:22:51+00:00

It is guarantee that the loop will stop at first iteration. So drop the
loop.

staging: wfx: fix AC priority

2020-06-16T19:22:50+00:00

In order to work properly all the queues of the device must be filled (the
device chooses itself the queue to use depending of AC parameters and
other things). It is the job of wfx_tx_queues_get_skb() to choose which
queue must be filled. However, the sorting algorithm was inverted, so it
prioritized the already filled queue! Consequently, the AC priorities was
badly broken.

staging: wfx: split wfx_get_ps_timeout() from wfx_update_pm()

2020-05-27T08:18:09+00:00

In the next commit, we will have to compute the PS timeout without
changing the power save status of the device. This patch introduces
wfx_get_ps_timeout() for that job and make wfx_update_pm() relies on it.

staging: wfx: retrieve the PS status from the vif

2020-05-27T08:18:09+00:00

The Power Save status is stored for each virtual interface and for the
whole device. The WF200 is able to handle power saving per interface, so
use the value stored in vif.

staging: wfx: add support for tx_power_loop

2020-05-27T08:18:08+00:00

During the calibration of the RF amplifier, the device is able to provide
some data about the status of the amplifier.

Record these data and expose them in debugfs.

2020-05-27T08:18:08+00:00

Since the commit 3f84adfe1d7ae ("staging: wfx: remove hack about tx_rate
policies"), the variable "count" is no more used in wfx_tx_policy_build().

Notice that there were two instances of the variable "count" in
wfx_tx_policy_build(). This patch also solves this cosmetic issue.
