net: dsa: Allow compiling out legacy support

2017-12-07T19:14:54+00:00

Introduce a configuration option: CONFIG_NET_DSA_LEGACY allowing to compile out support for the old platform device and Device Tree binding registration. Support for these configurations is scheduled to be removed in 4.17. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

dsa: add DSA switch driver for Microchip KSZ9477

2017-06-01T00:56:31+00:00

The KSZ9477 is a fully integrated layer 2, managed, 7 ports GigE switch with numerous advanced features. 5 ports incorporate 10/100/1000 Mbps PHYs. The other 2 ports have interfaces that can be configured as SGMII, RGMII, MII or RMII. Either of these may connect directly to a host processor or to an external PHY. The SGMII port may interface to a fiber optic transceiver. This driver currently supports vlan, fdb, mdb & mirror dsa switch operations.

net: dsa: LAN9303: add I2C dependency

net: dsa: LAN9303: add MDIO managed mode support

2017-04-20T17:48:55+00:00

When the LAN9303 device is in MDIO manged mode, all register accesses must be done via MDIO. Please note: this code is compile time tested only due to the absence of such configured hardware. It is based on a patch from Stefan Roese from 2014.

net-next: dsa: add dsa support for Mediatek MT7530 switch

2017-04-07T20:52:11+00:00

MT7530 is a 7-ports Gigabit Ethernet Switch that could be found on Mediatek router platforms such as MT7623A or MT7623N platform which includes 7-port Gigabit Ethernet MAC and 5-port Gigabit Ethernet PHY. Among these ports, The port from 0 to 4 are the user ports connecting with the remote devices while the port 5 and 6 are the CPU ports connecting into Mediatek Ethernet GMAC. For port 6, it can communicate with the CPU via Mediatek Ethernet GMAC through either the TRGMII or RGMII which could be controlled by phy-mode in the dt-bindings to specify which mode is preferred to use. And for port 5, only RGMII can be specified. However, currently, only port 6 is being supported in this DSA driver. The driver is made with the reference to qca8k and other existing DSA driver. The most of the essential callbacks of the DSA are already support in the driver, including tag insert for user port distinguishing, port control, bridge offloading, STP setup and ethtool operation to allow DSA to model each user port into a standalone netdevice as the other DSA driver had done.

net: dsa: Mock-up driver

2017-04-01T19:39:32+00:00

This patch adds support for a DSA mock-up driver which essentially does the following: - registers/unregisters 4 fixed PHYs to the slave network devices - uses eth0 (configurable) as the master netdev - registers the switch as a fixed MDIO device against the fixed MDIO bus at address 31 - includes dynamic debug prints for dsa_switch_ops functions that can be enabled to get call traces This is a good way to test modular builds as well as exercise the DSA APIs without requiring access to real hardware. This does not test the data-path, although this could be added later on. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net-next: dsa: add new driver for qca8xxx family

2016-09-16T08:31:51+00:00

This patch contains initial support for the QCA8337 switch. It will detect a QCA8337 switch, if present and declared in the DT. Each port will be represented through a standalone net_device interface, as for other DSA switches. CPU can communicate with any of the ports by setting an IP@ on ethN interface. Most of the extra callbacks of the DSA subsystem are already supported, such as bridge offloading, stp, fdb. Signed-off-by: John Crispin Signed-off-by: David S. Miller
