The code has the functionality to insert the GPIO lines using the global GPIO numbers through module parameters. As we are clearly deprecating the use of global GPIO numbers look up the GPIO descriptors from the device instead. This usually falls back to device hardware descriptions using e.g. device tree or ACPI. This device clearly supports device tree when used over SPI for example. For example, this can be supplied in the device tree like so: wfx@0x01 { compatible = "silabs,wf200"; reset-gpios = <&gpio0 1>; wakeup-gpios = <&gpio0 2>; }; Cc: Jérôme Pouiller <jerome.pouiller@silabs.com> Reviewed-by:Jérôme Pouiller <jerome.pouiller@silabs.com> Signed-off-by:

When multiple interface on different channels are in use. It is necessary to advertise the AP that the device is no more awake before to switch to the other channel. Until now, PS-Poll was the preferred mechanism for that. However. The new firmwares (>= 3.7) now nicely support FastPS. FastPS improves bandwidth and compatibility with AP. This patch drop the complex and rarely used mechanism introduced in the commit dd5eba1b ("staging: wfx: fix support for AP that do not support PS-Poll") and use FastPS as soon as it is possible.

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 However, this API is obsolete and it seems a little weird to use (it seems it does apply the change, so the user have to disable then re-enable de power save) On side of nl80211, there is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. Signed-off-by:

To enable the TKIP/CCMP replay protection, the frames has to be processed in the right order. However, the device is not able to re-order the frames during BlockAck sessions. Mac80211 is able to reorder the frames, but it need the information about the BlockAck sessions start and stop. Unfortunately, since the BlockAck is fully handled by the hardware, these frames were not forwarded to the host. So, if the driver ask to mac80211 to apply the replay protection, it drop all misordered frames. So, until now, the driver explicitly asked to mac80211 to not apply the CCMP/TKIP replay protection. The situation has changed with the API 3.4 of the device firmware. The firmware forward the BlockAck information. Mac80211 is now able to correctly reorder the frames. There is no more reasons to drop cryptographic data. This patch also impact the older firmwares. There will be a performance impact on these firmware (since the misordered frames will dropped). However, we can't keep the replay protection disabled. Signed-off-by:

We don't want mac80211 try to check MMIC and other security mechanisms. So, the driver remove all the data related to the encryption (IV, ICV, MMIC). However, enabling RX_FLAG_PN_VALIDATED is sufficient for that. So, drop the useless function wfx_drop_encrypt_data() and enable RX_FLAG_PN_VALIDATED. Signed-off-by:

It seems that in the old days, the RSSI information could be missing. In this case, in order to not pollute the RSSI stats, the frame was dropped (!). It is far better to mark the frame with the flag RX_FLAG_NO_SIGNAL_VAL. In add, the problem seems now fixed in the firmware (at least, it has not been encountered with recent firmwares).

Since the driver does not call ieee80211_sta_set_buffered() anymore, it is no more necessary to maintain a counter of buffered frames for each stations. This change allows to simplify the processing in multiple places in the driver. Signed-off-by:

Jérôme Pouiller authored
When a station go to sleep, the driver receive the status REQUEUE and forward this answer to mac80211. So, neither the driver, neither the hardware buffer the frames. So the call to ieee80211_sta_set_buffered is useless. In add, it seems that mac80211 does not expect to receive ieee80211_sta_set_buffered(false) after the station is asleep(). When the device send data to a station, the following sequence can be observed: - Mac80211 call wfx_sta_notify(awake). - The driver calls ieee80211_sta_set_buffered(true). Since the station is awake, its TIM is not set. - Mac80211 receive a power save notification from the station, so it calls wfx_sta_notify(asleep). - Then, since the driver has declared it has buffered some frames, the TIM of the station should be set. This action is delayed by mac80211. - The device also notice the station go to sleep. It replies the REQUEUE status for the buffered frames. The driver forward this status to mac80211. - There is no more frames in queues, so the driver call ieee80211_sta_set_buffered(false). - Mac80211 updates the TIM but since there is no frames buffered by the driver, it set the TIM for the station to 0. Anyway, correctly use the ieee80211_sta_set_buffered() API solves the problem. Signed-off-by: -
