net: dsa: initial support for MT7628 embedded switch

2026-08-18T13:50:13Z

Add support for the MT7628 embedded switch. The switch has 5 built-in 100Mbps user ports (ports 0-4) and one 1Gbps port that is internally attached to the SoCs CPU MAC and serves as the CPU port. The switch hardware has a very limited 16 entry VLAN table. Configuring VLANs is the only way to control switch forwarding. Currently 6 entries are used by tag_8021q to isolate the ports. Double tag feature is enabled to force the switch to append the VLAN tag even if the incoming packet is already tagged, this simulates VLAN-unaware functionality and simplifies the tagger implementation.

net: dsa: netc: introduce NXP NETC switch driver for i.MX94

2026-05-21T11:04:42Z

For i.MX94 series, the NETC IP provides full 802.1Q Ethernet switch functionality, advanced QoS with 8 traffic classes, and a full range of TSN 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 the internal ENETC are fully integrated within the NETC IP, no back-to-back MAC connection is required. Instead, a light-weight "pseudo MAC" is used between the switch and the ENETC. This translates to lower power (less logic and memory) and lower delay (as there is no serialization delay across this link). Introduce the initial NETC switch driver with basic probe and remove functionality. More features will be added in subsequent patches.

net: dsa: add basic initial driver for MxL862xx switches

2026-02-11T10:27:58Z

Add very basic DSA driver for MaxLinear's MxL862xx switches. In contrast to previous MaxLinear switches the MxL862xx has a built-in processor that runs a sophisticated firmware based on Zephyr RTOS. Interaction between the host and the switch hence is organized using a software API of that firmware rather than accessing hardware registers directly. Add descriptions of the most basic firmware API calls to access the built-in MDIO bus hosting the 2.5GE PHYs, basic port control as well as setting up the CPU port. Implement a very basic DSA driver using that API which is sufficient to get packets flowing between the user ports and the CPU port. The firmware offers all features one would expect from a modern switch hardware, they are going to be added one by one in follow-up patch series.

Move the lantiq_gswip driver to its own folder and update MAINTAINERS file accordingly. This is done ahead of extending the driver to support the MaxLinear GSW1xx series of standalone switch ICs, which includes adding a bunch of files.

net: dsa: ks8995: Add basic switch set-up

2025-08-19T00:26:09Z

We start to extend the KS8995 driver by simply registering it as a DSA device and implementing a few switch callbacks for STP set-up and such to begin with. No special tags or other advanced stuff: we use DSA_TAG_NONE and rely on the default set-up in the switch with the special DSA tags turned off. This makes the switch wire up properly to all its PHY's and simple bridge traffic works properly. After this the bridge DT bindings are respected, ports and their PHYs get connected to the switch and react appropriately through the phylib when cables are plugged in etc. Tested like this in a hacky OpenWrt image: Bring up conduit interface manually: ixp4xx_eth c8009000.ethernet eth0: eth0: link up, speed 100 Mb/s, full duplex spi-ks8995 spi0.0: enable port 0 spi-ks8995 spi0.0: set KS8995_REG_PC2 for port 0 to 06 spi-ks8995 spi0.0 lan1: configuring for phy/mii link mode spi-ks8995 spi0.0 lan1: Link is Up - 100Mbps/Full - flow control rx/tx PING 169.254.1.1 (169.254.1.1): 56 data bytes 64 bytes from 169.254.1.1: seq=0 ttl=64 time=1.629 ms 64 bytes from 169.254.1.1: seq=1 ttl=64 time=0.951 ms I also tested SSH from the device to the host and it works fine. It also works fine to ping the device from the host and to SSH into the device from the host. This brings the ks8995 driver to a reasonable state where it can be used from the current device tree bindings and the existing device trees in the kernel.

net: dsa: Move KS8995 to the DSA subsystem

2025-08-19T00:26:09Z

By reading the datasheets for the KS8995 it is obvious that this is a 100 Mbit DSA switch. Let us start the refactoring by moving it to the DSA subsystem to preserve development history. Verified that the chip still probes the same after this patch provided CONFIG_HAVE_NET_DSA, CONFIG_NET_DSA and CONFIG_DSA_KS8995 are selected.
