net: dsa: Fix dsa_is_user_port() test inversion

2018-03-13T01:04:55+00:00

During the conversion to dsa_is_user_port(), a condition ended up being reversed, which would prevent the creation of any user port when using the legacy binding and/or platform data, fix that. Fixes: 4a5b85ffe2a0 ("net: dsa: use dsa_is_user_port everywhere") Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: dsa: Support internal phy on 'cpu' port

2018-01-24T00:22:38+00:00

This adds support for enabling the internal PHY for a 'cpu' port. It has been tested on GE B850v3, B650v3 and B450v3, which have a built-in MV88E6240 switch hardwired to a PCIe based network card. On these machines the internal PHY of the i210 network card and the Marvell switch are connected to each other and must be enabled for properly using the switch. While the i210 PHY will be enabled when the network interface is enabled, the switch's port is not exposed as network interface. Additionally the mv88e6xxx driver resets the chip during probe, so the PHY is disabled without this patch. Signed-off-by: Sebastian Reichel Reviewed-by: Florian Fainelli Signed-off-by: David S.

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

net: dsa: Pass a port to get_tag_protocol()

2017-11-13T01:34:54+00:00

A number of drivers want to check whether the configured CPU port is a possible configuration for enabling tagging, pass down the CPU port number so they verify that. Signed-off-by: Florian Fainelli Reviewed-by: Vivien Didelot Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: dsa: setup and teardown master device

2017-11-09T00:26:49+00:00

Add DSA helpers to setup and teardown a master net device wired to its CPU port. This centralizes the dsa_ptr assignment. This also makes the master ethtool helpers static at the same time. Signed-off-by: Vivien Didelot Signed-off-by: David S. Miller

net: dsa: remove name arg from slave create

2017-11-01T02:47:36+00:00

Now that slave dsa_port always have their name set, there is no need to pass it to dsa_slave_create() anymore. Remove this argument. Signed-off-by: Vivien Didelot Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller

net: dsa: get port name at parse time

2017-11-01T02:47:36+00:00

Get the optional "label" property and assign a default one directly at parse time instead of doing it when creating the slave. For legacy, simply assign the port name stored in cd->port_names. Signed-off-by: Vivien Didelot Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller

net: dsa: move fixed link registration helpers

2017-10-28T09:50:12+00:00

The new bindings (dsa2.c) and the old bindings (legacy.c) share two helpers dsa_cpu_dsa_setup and dsa_cpu_dsa_destroy, used to register or deregister a fixed PHY if a given port has a corresponding device node. Unclutter the code by moving them into two new port.c helpers, dsa_port_fixed_link_register_of and dsa_port_fixed_link_(un)register_of. Signed-off-by: Vivien Didelot Signed-off-by: David S. Miller

net: dsa: remove port masks

2017-10-27T15:00:09+00:00

Now that DSA core provides port types, there is no need to keep this information at the switch level. This is a static information that is part of a DSA core dsa_port structure. Remove them. Signed-off-by: Vivien Didelot Signed-off-by: David S. Miller

net: dsa: define port types

2017-10-27T15:00:09+00:00

Introduce an enumerated type for ports, which will be way more explicit to identify a port type instead of digging into switch port masks. A port can be of type CPU, DSA, user, or unused by default. This is a static parsed information that cannot be changed at runtime. Signed-off-by: Vivien Didelot Signed-off-by: David S. Miller
