Frames sent to userspace can be reported as dropped in ovs_dp_process_packet, however, if they are dropped in the netlink code then netlink_attachskb will report the same frame as dropped. This patch checks for error codes which indicate that the frame has already been freed. Signed-off-by:

Maxime Chevallier says: ==================== net: Introduce QUSGMII phy mode Re-sending, since the previous v4 was sent while net-next was closed. This is a resend of the V4 of a previous series [1] initially aimed at introducing inband extensions, with modes like QUSGMII. This mode allows passing info in the ethernet preamble between the MAC and the PHY, such as timestamps. This series has now become a preliminary series, that simply introduces the new interface mode, without support for inband extensions, that will come later. The reasonning is that work will need to be done in the networking subsystem, but also in the generic phy driver subsystem to allow serdes configuration for qusgmii. This series add the mode, the relevant binding changes, adds support for it in the lan966x driver, and also introduces a small helper to get the number of links a given phy mode can carry (think 1 for SGMII and 4 for QSGMII). This allows for better readability and will prove useful when (if) we support PSGMII (5 links on 1 interface) and OUSGMII (8 links on one interface). V4 contains no change but the collected Reviewed-by from Andrew. ==================== Signed-off-by: -

The Lan996x controller supports the QUSGMII mode, which is very similar to QSGMII in the way it's configured and the autonegociation capababilities it provides. This commit adds support for that mode, treating it most of the time like QSGMII, making sure that we do configure the PCS how we should. Signed-off-by:

Some phy modes such as QSGMII multiplex several MAC<->PHY links on one single physical interface. QSGMII used to be the only one supported, but other modes such as QUSGMII also carry multiple links. This helper allows getting the number of links that are multiplexed on a given interface. Signed-off-by:

Add a new QUSGMII mode, standing for "Quad Universal Serial Gigabit Media Independent Interface", a derivative of USGMII which, similarly to QSGMII, allows to multiplex 4 1Gbps links to a Quad-PHY. The main difference with QSGMII is that QUSGMII can include an extension instead of the standard 7bytes ethernet preamble, allowing to convey arbitrary data such as Timestamps. Signed-off-by:

The QUSGMII mode is a derivative of Cisco's USXGMII standard. This standard is pretty similar to SGMII, but allows for faster speeds, and has the build-in bits for Quad and Octa variants (like QSGMII). The main difference with SGMII/QSGMII is that USXGMII/QUSGMII re-uses the preamble to carry various information, named 'Extensions'. As of today, the USXGMII standard only mentions the "PCH" extension, which is used to convey timestamps, allowing in-band signaling of PTP timestamps without having to modify the frame itself. This commit adds support for that mode. When no extension is in use, it behaves exactly like QSGMII, although it's not compatible with QSGMII. Signed-off-by:

On the CPSW and ICSS peripherals, there is a possibility that the MDIO interface returns corrupt data on MDIO reads or writes incorrect data on MDIO writes. There is also a possibility for the MDIO interface to become unavailable until the next peripheral reset. The workaround is to configure the MDIO in manual mode and disable the MDIO state machine and emulate the MDIO protocol by reading and writing appropriate fields in MDIO_MANUAL_IF_REG register of the MDIO controller to manipulate the MDIO clock and data pins. More details about the errata i2329 and the workaround is available in: https://www.ti.com/lit/er/sprz487a/sprz487a.pdf Add implementation to disable MDIO state machine, configure MDIO in manual mode and achieve MDIO read and writes via MDIO Bitbanging Signed-off-by:

There are two ways that GRS can be set: graceful_stop and dtsec_isr. It is cleared by graceful_start. If it is already set before calling graceful_stop, then that means that dtsec_isr set it. In that case, we will not set GRS nor will we clear it (which seems like a bug?). For GTS the logic is similar, except that there is no one else messing with this bit (so we will always set and clear it). Simplify the logic by always setting/clearing GRS/GTS. This is less racy that the previous behavior, and ensures that we always end up clearing the bits. This can of course clear GRS while dtsec_isr is waiting, but because we have already done our own waiting it should be fine. This is the last user of enum comm_mode, so remove it. Signed-off-by:

Petr Machata says: ==================== selftests: mlxsw: Add ordering tests for unified bridge model Amit Cohen writes: Commit 798661c7 ("Merge branch 'mlxsw-unified-bridge-conversion-part-6'") converted mlxsw driver to use unified bridge model. In the legacy model, when a RIF was created / destroyed, it was firmware's responsibility to update it in the relevant FID classification records. In the unified bridge model, this responsibility moved to software. This set adds tests to check the order of configuration for the following classifications: 1. {Port, VID} -> FID 2. VID -> FID 3. VNI -> FID (after decapsulation) In addition, in the legacy model, software is responsible to update a table which is used to determine the packet's egress VID. Add a test to check that the order of configuration does not impact switch behavior. See more details in the commit messages. Note that the tests supposed to pass also using the legacy model, they are added now as with the new model they test the driver and not the firmware. Patch set overview: Patch #1 adds test for {Port, VID} -> FID Patch #2 adds test for VID -> FID Patch #3 adds test for VNI -> FID Patch #4 adds test for egress VID classification ==================== Link: https://lore.kernel.org/r/cover.1660747162.git.petrm@nvidia.comSigned-off-by:

After routing, the device always consults a table that determines the packet's egress VID based on {egress RIF, egress local port}. In the unified bridge model, it is up to software to maintain this table via REIV register. The table needs to be updated in the following flows: 1. When a RIF is set on a FID, for each FID's {Port, VID} mapping, a new {RIF, Port}->VID mapping should be created. 2. When a {Port, VID} is mapped to a FID and the FID already has a RIF, a new {RIF, Port}->VID mapping should be created. Add a test to verify that packets get the correct VID after routing, regardless of the order of the configuration. # ./egress_vid_classification.sh TEST: Add RIF for existing {port, VID}->FID mapping [ OK ] TEST: Add {port, VID}->FID mapping for FID with a RIF [ OK ] Signed-off-by:Amit Cohen <amcohen@nvidia.com> Reviewed-by:

After classification, the FID is known, but also all the attributes of the FID, such as the router interface (RIF) via which a packet that needs to be routed will ingress the router block. For VXLAN decapsulation, the FID classification is done according to the VNI. When a RIF is added on top of a FID, the existing VNI->FID mapping should be updated by the software with the new RIF. In addition, when a new mapping is added for FID which already has a RIF, the correct RIF should be used for it.

Wei Fang says: ==================== Add DT property to disable hibernation mode The patches add the ability to disable the hibernation mode of AR803x PHYs. Hibernation mode defaults to enabled after hardware reset on these PHYs. If the AR803x PHYs enter hibernation mode, they will not provide any clock. For some MACs, they might need the clocks which provided by the PHYs to support their own hardware logic. So, the patches add the support to disable hibernation mode by adding a boolean: qca,disable-hibernation-mode If one wished to disable hibernation mode to better match with the specifical MAC, just add this property in the phy node of DT. ==================== Link: https://lore.kernel.org/r/20220818030054.1010660-1-wei.fang@nxp.comSigned-off-by: -

When the cable is unplugged, the Atheros AR803x PHYs will enter hibernation mode after about 10 seconds if the hibernation mode is enabled and will not provide any clock to the MAC. But for some MACs, this feature might cause unexpected issues due to the logic of MACs. Taking SYNP MAC (stmmac) as an example, if the cable is unplugged and the "eth0" interface is down, the AR803x PHY will enter hibernation mode. Then perform the "ifconfig eth0 up" operation, the stmmac can't be able to complete the software reset operation and fail to init it's own DMA. Therefore, the "eth0" interface is failed to ifconfig up. Why does it cause this issue? The truth is that the software reset operation of the stmmac is designed to depend on the RX_CLK of PHY. So, this patch offers an option for the user to determine whether to disable the hibernation mode of AR803x PHYs. Signed-off-by:

The hibernation mode of Atheros AR803x PHYs defaults to be enabled after hardware reset. When the cable is unplugged, the PHY will enter hibernation mode after about 10 seconds and the PHY clocks will be stopped to save power. However, some MACs need the phy output clock for proper functioning of their logic. For instance, stmmac needs the RX_CLK of PHY for software reset to complete. Therefore, add a DT property to configure the PHY to disable this hardware hibernation mode. Signed-off-by:
