net: dsa: Discard frames from unused ports

2018-04-12T10:29:59+00:00

[ Upstream commit fc5f33768cca7144f8d793205b229d46740d183b ] The Marvell switches under some conditions will pass a frame to the host with the port being the CPU port. Such frames are invalid, and should be dropped. Not dropping them can result in a crash when incrementing the receive statistics for an invalid port.

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: Fix dsa_legacy_register() return value

2018-01-03T02:52:48+00:00

We need to make the dsa_legacy_register() stub return 0 in order for dsa_init_module() to successfully register and continue registering the ETH_P_XDSA packet handler.

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: Support prepended Broadcom tag

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

Add a new type: DSA_TAG_PROTO_PREPEND which allows us to support for the 4-bytes Broadcom tag that we already support, but in a format where it is pre-pended to the packet instead of located between the MAC SA and the Ethertyper (DSA_TAG_PROTO_BRCM).

net: dsa: add more const attributes

2017-11-10T04:41:40+00:00

The notify mechanism does not need to modify the port it is notifying. So make the parameter const. Signed-off-by: Andrew Lunn Reviewed-by: Vivien Didelot 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: 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: split dsa_port's netdev member

2017-10-18T11:24:33+00:00

The dsa_port structure has a "netdev" member, which can be used for either the master device, or the slave device, depending on its type. It is true that today, CPU port are not exposed to userspace, thus the port's netdev member can be used to point to its master interface. But it is still slightly confusing, so split it into more explicit "master" and "slave" members inside an anonymous union. Signed-off-by: Vivien Didelot Signed-off-by: David S. Miller
