* net: dsa: Plug in PHYLINK supportFlorian Fainelli2018-05-111-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | Add support for PHYLINK within the DSA subsystem in order to support more complex devices such as pluggable (SFP) and non-pluggable (SFF) modules, 10G PHYs, and traditional PHYs. Using PHYLINK allows us to drop some amount of complexity we had while probing fixed and non-fixed PHYs using Device Tree. Because PHYLINK separates the Ethernet MAC/port configuration into different stages, we let switch drivers implement those, and for now, we maintain functionality by calling dsa_slave_adjust_link() during phylink_mac_link_{up,down} which provides semantically equivalent steps. Drivers willing to take advantage of PHYLINK should implement the phylink_mac_* operations that DSA wraps. We cannot quite remove the adjust_link() callback just yet, because a number of drivers rely on that for configuring their "CPU" and "DSA" ports, this is done dsa_port_setup_phy_of() and dsa_port_fixed_link_register_of() still. Drivers that utilize fixed links for user-facing ports (e.g: bcm_sf2) will need to implement phylink_mac_ops from now on to preserve functionality, since PHYLINK *does not* create a phy_device instance for fixed links.

* net: dsa: Discard frames from unused portsAndrew Lunn2018-04-081-1/+7
| | | | | | | | | | | | | 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' portSebastian Reichel2018-01-231-2/+2
| | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | With DSA, a master net device (CPU facing interface) has a dsa_ptr pointer to which hangs a dsa_switch_tree.

Change the master interface's dsa_ptr for the CPU dsa_port pointer. This is a step towards supporting multiple CPU ports.

This makes the tagging rcv functions more concise and robust, and also makes dsa_get_cpu_port obsolete.

* net: dsa: add notifier for ageing timeVivien Didelot2017-05-221-0/+8
| | | | | | | | | | | | | | | | This patch keeps the port-wide ageing time handling code in dsa_port_ageing_time, pushes the requested ageing time value in a new switch fabric notification, and moves the switch-wide ageing time handling code in dsa_switch_ageing_time. This has the effect that now not only the switch that the target port belongs to can be programmed, but all switches composing the switch fabric. For the moment, keep the current behavior and ignore other switches.

* net: dsa: move notifier info to private headerVivien Didelot2017-05-221-0/+12
| | | | | | | | | | | | | | | The DSA notifier events and info structure definitions are not meant for DSA drivers and users, but only used internally by the DSA core files. Move them from the public net/dsa.h file to the private dsa_priv.h file. Also use this opportunity to turn the events into an anonymous enum, because we don't care about the values, and this will prevent future conflicts when adding (and sorting) new events.
