2020-01-16net/mlx5: fs_core: Introduce unmanaged flow tablesPaul Blakey
Currently, Most of the steering tree is statically declared ahead of time, with steering prios instances allocated for each fdb chain to assign max number of levels for each of them. This allows fs_core to manage the connections and levels of the flow tables hierarcy to prevent loops, but restricts us with the number of supported chains and priorities. Introduce unmananged flow tables, allowing the user to manage the flow table connections. A unamanged table is detached from the fs_core flow table hierarcy, and is only connected back to the hierarchy by explicit FTEs forward actions. This will be used together with firmware that supports ignoring the flow table levels to increase the number of supported chains and prios.

2020-01-17software node: introduce CONFIG_KUNIT_DRIVER_PE_TESTAlan Maguire
Currently the property entry kunit tests are built if CONFIG_KUNIT=y. This will cause warnings when merged with the kunit tree that now supports tristate CONFIG_KUNIT. While the tests appear to compile as a module, we get a warning about missing module license. It's better to have a per-test suite CONFIG variable so that we can do selective building of kunit-based suites, and can also avoid merge issues like this.

The allocated normal volumes saved in ubi->volumes are not freed in the error paths in ubi_attach_mtd_dev() and its callees (e.g. ubi_attach() and ubi_read_volume_table()). These normal volumes should be freed through kill_volumes() and vol_release(), but ubi_attach_mtd_dev() may fail before calling uif_init(), and there will be memory leaks. So adding a new helper ubi_free_all_volumes() to free the normal and the internal volumes. And in order to prevent double-free of volume, reset ubi->volumes[i] to NULL after freeing.

Keep buffered all frames marked "after dtim" 3. When it receive a suspend_resume indication (see wfx_suspend_resume_mc()), send all the buffered frames. This indication is sent by the firmware 4ms before the dtim. 4. If one of the frames returns status "REQUEUE", it means that the DTIM period was ended before to be able to send the frame. 5. When all the buffered frames were sent or if DTIM period was ended, driver should update the TIM with multicast bit reset. All the mess with the asynchronous works can be dropped.

However, mac80211 already handles power save status of stations and this behavior has been removed from the firmware. So now, when suspend_resume indication is received, it is always to notify that a DTIM is about to be sent. So, it is possible to simply wfx_suspend_resume().

2020-01-16staging: wfx: simplify the link-id allocationJérôme Pouiller
The "link-id" is a slot number provided to the chip. A link-id is allocated to every station associated with the chip (mainly when the chip is in AP mode). It is more or less the same thing than the association ID, but it is limited to 14 values. Firmware uses the link-id to track the power save status of the stations. The current code try to associate a link-id as soon as data are exchanged with station. It is far easier to rely on sta_add() and sta_remove(). Until now the value WFX_LINK_ID_NO_ASSOC, was only used when no more link-id was available. Now, we also use this value for not-yet-associated stations (that was its primary behavior).

2020-01-16staging: wfx: fix case where RTS threshold is 0Jérôme Pouiller
If RTS threshold is 0, it currently disables RTS. It should mean "enabled for every frames". Signed-off-by: Jérôme Pouiller <jerome.pouiller@silabs.com> Link: https://lore.kernel.org/r/20200115135338.14374-44-Jerome.Pouiller@silabs.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2020-01-16staging: wfx: do not update uapsd if not necessaryJérôme Pouiller
wfx_conf_tx() is called for each queue. On every call, the function updates UAPSD mask and PM mode for all queues. It is a pity since the UAPSD configuration very rarely changes and it makes exchanges between the host and the chip more difficult to track. This patch avoid to update UAPSD and Power Mode in most usual cases.

2020-01-16staging: wfx: with multiple vifs, force PS only if channels differsJérôme Pouiller
When multiple vif are in use (the only supported configuration is one station and one AP), the driver force power save flag on station. This behavior allows the station to leave the station channel and make its business on AP channel. However, this has a big impact on station performances (especially since only legacy PS is supported). When both vifs use the same channel, it is not necessary to keep this restriction. This greatly improve station performances.

2020-01-16staging: wfx: update power-save per interfaceJérôme Pouiller
mac80211 and the device are both able to control power-save per vif. But, the current code retrieve power-save from wfx_config(). So, it does not allow to setup power-save independently for each vif. Driver just has to rely on wfx_bss_info_changed() instead of wfx_config(). wfx_config() has nothing to do anymore, but we keep it since it is mandatory for mac80211.

HIF functions return only serious errors (OOM or device freeze). The current handling of errors in wfx_set_mcast_filter() does not bring anything. Finally it may disturb the developer more than it helps.
