Mon, 18 May 2026 10:25:01 +0200

net: dsa: netc: introduce NXP NETC switch driver for i.MX94For i.MX94 series, the NETC IP provides full 802.1Q Ethernet switchfunctionality, advanced QoS with 8 traffic classes, and a full range ofTSN standards capabilities. The switch has 3 user ports and 1 CPU port,the CPU port is connected to an internal ENETC. Since the switch and theinternal ENETC are fully integrated within the NETC IP, no back-to-backMAC connection is required. Instead, a light-weight "pseudo MAC" is usedbetween the switch and the ENETC. This translates to lower power (lesslogic and memory) and lower delay (as there is no serialization delayacross this link).Introduce the initial NETC switch driver with basic probe and removefunctionality. More features will be added in subsequent patches.Signed-off-by: Wei Fang Link: https://patch.msgid.link/20260518082506.1318236-11-wei.fang@nxp.comSigned-off-by: Paolo Abeni List of files: /linux/drivers/net/dsa/Makefile

Sat, 07 Feb 2026 04:07:27 +0100

net: dsa: add basic initial driver for MxL862xx switchesAdd very basic DSA driver for MaxLinear's MxL862xx switches.In contrast to previous MaxLinear switches the MxL862xx has a built-inprocessor that runs a sophisticated firmware based on Zephyr RTOS.Interaction between the host and the switch hence is organized using asoftware API of that firmware rather than accessing hardware registersdirectly.Add descriptions of the most basic firmware API calls to access thebuilt-in MDIO bus hosting the 2.5GE PHYs, basic port control as well assetting up the CPU port.Implement a very basic DSA driver using that API which is sufficient toget packets flowing between the user ports and the CPU port.The firmware offers all features one would expect from a modern switchhardware, they are going to be added one by one in follow-up patchseries.Signed-off-by: Daniel Golle Link: https://patch.msgid.link/ccde07e8cf33d8ae243000013b57cfaa2695e0a9.1770433307.git.daniel@makrotopia.orgReviewed-by: Vladimir Oltean Signed-off-by: Paolo Abeni List of files: /linux/drivers/net/dsa/Makefile

Mon, 18 Oct 2021 11:38:01 +0200

net: dsa: realtek-smi: add rtl8365mb subdriver for RTL8365MB-VCThis patch adds a realtek-smi subdriver for the RTL8365MB-VC 4+1 port10/100/1000M switch controller. The driver has been developed based on aGPL-licensed OS-agnostic Realtek vendor driver known as rtl8367c foundin the OpenWrt source tree.Despite the name, the RTL8365MB-VC has an entirely different registerlayout to the already-supported RTL8366RB ASIC. Notwithstanding this,the structure of the rtl8365mb subdriver is loosely based on the rtl8366rbsubdriver. Like the 'rb, it establishes its own irqchip to handlecascaded PHY link status interrupts.The RTL8365MB-VC switch is capable of offloading a large number offeatures from the software, but this patch introduces only the mostbasic DSA driver functionality. The ports always function as standaloneports, with bridging handled in software.One more thing. Realtek's nomenclature for switches makes it hard toknow exactly what other ASICs might be supported by this driver. Thevendor driver goes by the name rtl8367c, but as far as I can tell, nochip actually exists under this name. As such, the subdriver is namedrtl8365mb to emphasize the potentially limited support. But it is clearfrom the vendor sources that a number of other more advanced switchesshare a similar register layout, and further support should not be toohard to add given access to the relevant hardware. With this in mind,the subdriver has been written with as few assumptions about theparticular chip as is reasonable. But the RTL8365MB-VC is the onlyhardware I have available, so some further work is surely needed.Co-developed-by: Michael Rasmussen Signed-off-by: Michael Rasmussen Signed-off-by: Alvin Šipraga Reviewed-by: Vladimir Oltean Reviewed-by: Linus Walleij Reviewed-by: Florian Fainelli Tested-by: Arınç ÜNAL Signed-off-by: David S.

56051948773eeb4224fbda88102e891d1ad5cefd - net: dsa: ocelot: add driver for Felix switch family

Thu, 14 Nov 2019 16:03:30 +0100

net: dsa: ocelot: add driver for Felix switch familyThis supports an Ethernet switching core from Vitesse / Microsemi /Microchip (VSC9959) which is part of the Ocelot family (a brand name),and whose code name is Felix. The switch can be (and is) integrated ondifferent SoCs as a PCIe endpoint device.The functionality is provided by the core of the Ocelot switch driver(drivers/net/ethernet/mscc). In this regard, the current driver is aninstance of Microsemi's Ocelot core driver, with a DSA front-end. Itinherits its name from VSC9959's code name, to distinguish itself fromthe switchdev ocelot driver.The patch adds the logic for probing a PCI device and defines theregister map for the VSC9959 switch core, since it has some differencesin register addresses and bitfield mappings compared to the other Ocelotswitches (VSC7511, VSC7512, VSC7513, VSC7514).The Felix driver declares the register map as part of the "instancetable". Currently the VSC9959 inside NXP LS1028A is the only instance,but presumably it can support other switches in the Ocelot family, whenused in DSA mode (Linux running on the external CPU, and not on theembedded MIPS).In a few cases, some h/w operations have to be done differently onVSC9959 due to missing bitfields. This is the case for the switch corereset and init. Because for this operation Ocelot uses some bits thatare not present on Felix, the latter has to use a register from theglobal registers block (GCB) instead.Although it is a PCI driver, it relies on DT bindings for compatibilitywith DSA (CPU port link, PHY library). It does not have any customdevice tree bindings, since we would like to minimize its dependency ondevice tree though.Signed-off-by: Claudiu Manoil Signed-off-by: Vladimir Oltean Signed-off-by: David S.
