staging: wfx: add a debugfs entry to force ps_timeout

2020-07-03T08:33:08+00:00

In some advanced usage or debug scenarios, it could interesting to
change the value of ps_timeout or eventually to force use of PS-Poll
frames.

The wext API (used by iwconfig) provide a way to change ps_timeout.
However, this API is obsolete and it seems a little weird to use (it
seems it does apply the change, so the user have to disable then
re-enable de power save)

On side of nl80211, there is no way to change the ps_timeout.

This patch provides a file in debugfs to change the value of ps_timeout.

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.

Indeed, the attribute len is little-endian. We have to take to the
endianness when we access it.

staging: wfx: fix output of rx_stats on big endian hosts

2020-05-13T11:49:43+00:00

The struct hif_rx_stats contains only little endian values. Thus, it is
necessary to fix byte ordering before to use them.

2020-04-28T12:14:28+00:00

The struct hif_mib_extended_count_table contains some debug information
accessible from the debugfs. The struct contains not yet used fields at
the end. In order to support future firmware versions, this patch also
show these not yet named fields.

staging: wfx: show counters of all interfaces

2020-04-28T12:14:28+00:00

The device keep up to date three series of stats. One for each
virtual interface and one for the whole device.

Until to now, the stats for the whole device were unavailable. Moreover,
it is interesting to retrieve counters for all interfaces even if they
are not awake.

Change the counters available in debugfs in order to retrieve stats
from all interfaces.

staging: wfx: revert unexpected change in debugfs output

2020-01-16T19:59:45+00:00

It appears that commit 8c7128c4cf4e ("staging: align to fix warnings of
line over 80 characters") do slightly more than what is explained in
commit log.

Especially, it changes the output of the file rx_stats from debugfs.
From some point of view, this file can be considered as a part of the
API. Any change on it should be clearly announced.

Since the change introduced does not seems to have any justification,
revert it.
