Horatiu Vultur says: ==================== net: lan966x: Add support for IS1 VCAP Provide the Ingress Stage 1 (IS1) VCAP (Versatile Content-Aware Processor) support for the Lan966x platform. The IS1 VCAP has 3 lookups and they are accessible with a TC chain id: - chain 1000000: IS1 Lookup 0 - chain 1100000: IS1 Lookup 1 - chain 1200000: IS1 Lookup 2 The IS1 is capable of different actions like rewrite VLAN tags, change priority of the frames, police the traffic, etc. These features will be added at a later point. The IS1 currently implements the action that allows setting the value of a PAG (Policy Association Group) key field in the frame metadata and this can be used for matching in an IS2 VCAP rule. In this way a rule in IS0 VCAP can be linked to rules in the IS2 VCAP. The linking is exposed by using the TC "goto chain" action with an offset from the IS2 chain ids. For example "goto chain 8000001" will use a PAG value of 1 to chain to a rule in IS2 lookup 0. ==================== Link: https://lore.kernel.org/r/20230307220929.834219-1-horatiu.vultur@microchip.com Signed-off-by:

NVMEM layouts are no longer registered early, and thus may not yet be available when Ethernet drivers (or any other consumer) probe, leading to possible probe deferrals errors. Forward the error code if this happens. All other errors being discarded, the driver will eventually use a random MAC address if no other source was considered valid (no functional change on this regard). Signed-off-by:

As it says in rfc8260#section-3.6 about the weighted fair queueing scheduler: A Weighted Fair Queueing scheduler between the streams is used. The weight is configurable per outgoing SCTP stream. This scheduler considers the lengths of the messages of each stream and schedules them in a specific way to use the capacity according to the given weights. If the weight of stream S1 is n times the weight of stream S2, the scheduler should assign to stream S1 n times the capacity it assigns to stream S2. The details are implementation dependent. Interleaving user messages allows for a better realization of the capacity usage according to the given weights. This patch adds Weighted Fair Queueing Scheduler actually based on the code of Fair Capacity Scheduler by adding fc_weight into struct sctp_stream_out_ext and taking it into account when sorting stream-> fc_list in sctp_sched_fc_sched() and sctp_sched_fc_dequeue_done().

As it says in rfc8260#section-3.5 about the fair capacity scheduler: A fair capacity distribution between the streams is used. This scheduler considers the lengths of the messages of each stream and schedules them in a specific way to maintain an equal capacity for all streams. The details are implementation dependent. interleaving user messages allows for a better realization of the fair capacity usage. This patch adds Fair Capacity Scheduler based on the foundations added by commit 5bbbbe32 ("sctp: introduce stream scheduler foundations"): A fc_list and a fc_length are added into struct sctp_stream_out_ext and a fc_list is added into struct sctp_stream. In .enqueue, when there are chunks enqueued into a stream, this stream will be linked into stream-> fc_list by its fc_list ordered by its fc_length. In .dequeue, it always picks up the 1st skb from stream->fc_list. In .dequeue_done, fc_length is increased by chunk's len and update its location in stream->fc_list according to the its new fc_length. Note that when the new fc_length overflows in .dequeue_done, instead of resetting all fc_lengths to 0, we only reduced them by U32_MAX / 4 to avoid a moment of imbalance in the scheduling, as Marcelo suggested.

Russell King says: ==================== Various mtk_eth_soc cleanups Here are a number of patches that do a bit of cleanup to mtk_eth_soc. The first patch cleans up mtk_gmac0_rgmii_adjust(), which is the troublesome function preventing the driver becoming a post-March2020 phylink driver. It doesn't solve that problem, merely makes the code easier to follow by getting rid of repeated tenary operators. The second patch moves the check for DDR2 memory to the initialisation of phylink's supported_interfaces - if TRGMII is not possible for some reason, we should not be erroring out in phylink MAC operations when that can be determined prior to phylink creation. The third patch removes checks from mtk_mac_config() that are done when initialising supported_interfaces - phylink will not call mtk_mac_config() with an interface that was not marked as supported, so these checks are redundant. The last patch removes the remaining vestiges of REVMII and RMII support, which appears to be entirely unused. These shouldn't conflict with Daniel's patch set, but if they do I will rework as appropriate. ==================== Link: https://lore.kernel.org/r/ZAdj9qUXcHUsK7Gt@shell.armlinux.org.uk Signed-off-by:

Since the conversion of mtk_eth_soc to phylink's supported_interfaces bitmap, these two modes have not been selectable. No one has raised this as an issue. Checking the in-kernel DT files, none of them use either of these modes with this hardware. Daniel Golle concurs: A quick grep through the device trees of the more than 650 ramips and mediatek boards we support in OpenWrt has revealed that *none* of them uses either reduced-MII or reverse-MII PHY modes. I could imaging that some more specialized ramips boards may use the RMII 100M PHY mode to connect with exotic PHYs for industrial or automotive applications (think: for 100BASE-T1 PHY connected via RMII). I have never seen or touched such boards, but there are hints that they do exist. For reverse-MII there are cases in which the Ralink SoC (Rt305x, for example) is used in iNIC mode, ie. connected as a PHY to another SoC, and running only a minimal firmware rather than running Linux. Due to the lack of external DRAM for the Ralink SoC on this kind of boards, the Ralink SoC there will anyway never be able to boot Linux. I've seen this e.g. in multimedia devices like early WiFi-connected not-yet-so-smart TVs. Consequently, the conclusion is that no one uses these modes with this hardware, so we might as well drop support for them. Signed-off-by:
