* net: dsa: mv88e6xxx: Disable Message Port bit for CPU portGuenter Roeck2015-03-291-4/+3Star
| | | | | | | | | | | | | | | | Datasheet says that the Message Port bit should not be set for the CPU port. Having it set causes DSA tagged packets to be sent to the CPU port roughly every 30 seconds. Those packets are the same as real packets forwarded between switch ports if the switch is configured for switching between multiple ports. The packets are then bridged by the software bridge, resulting in duplicated packets on the network.

| | | | | | | | | | | | | | | | | | | | | | | | Reading 64-bits register was not working because we inverted the steps between reading the lower 32-bits of the register and reading the upper 32-bits. Swapping these operations is how the HW guarantees that 64-bits reads are latched correctly. We only have a handful of 64-bits registers for now, mostly MIB counters, so the imapct is low.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement the bridge join, leave and set_stp callbacks by making that we do the following: - when a port joins the bridge, all existing ports in the bridge get their VLAN control register updated with that joining port - the joining port is including all existing bridge ports in its own VLAN control register The leave operation is fairly similar, special care must be taken to make sure that port leaving the bridging is not removing itself from its own VLAN control register. Since the various BR_* states apply directly to our HW semantics, we just need to translate these constants into their corresponding HW settings, and voila! We make sure to trigger a fast-ageing process for ports that are joining/leaving the bridge and transition from incompatible states, this is equivalent to triggering an ARL flush for that port.

In order to make sure we get proper LED link/activity signaling during suspend, switch the link indication from the Switch/MAC to the PHY. Finally, since the GPHY needs to be reset to be put in low power mode, we will loose any context applied to it: workarounds, EEE etc.. so we need to call phy_init_hw() to get our fixups re-applied successfully.

However, in some cases it uses to_mii_bus to perform that conversion. Since host_dev is not the phy bus device but typically a platform device, this fails and results in a crash with the affected drivers.

* net: dsa: bcm_sf2: add support for controlling EEEFlorian Fainelli2014-09-283-0/+79
| | | | | | | | | | | | | When EEE is enabled, negotiate this feature with the PHY and make sure that the capability checking, local EEE advertisement, link partner EEE advertisement and auto-negotiation resolution returned by phy_init_eee() is positive, and enable EEE at the switch level. While querying the current EEE settings, verify the low-power indication and indicate its status. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

* net: dsa: bcm_sf2: add port_enable/disable callbacksFlorian Fainelli2014-09-281-20/+40
| | | | | | | | | | | | | | | The SF2 switch driver is already architected around per-port enable/disable callbacks, so we just need a slight update to our existing bcm_sf2_port_setup() resp. bcm_sf2_port_disable() functions to be suitable as callbacks for port_enable/port_disable. We need to shuffle a little the code that does the per-port VLAN configuration/isolation since ports can now be brought up/down separately, so we need to make sure that IMP (CPU, management) port is always included in that specific port setup.

| | | | | | | | | When the link is down, disable the RGMII interface to conserve as much power as possible. We re-enable the RGMII interface whenever the link is detected. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* net: dsa: bcm_sf2: add support for Wake-on-LANFlorian Fainelli2014-09-222-0/+61
| | | | | | | | | | | | | | | In order for Wake-on-LAN to work properly, we query the parent network device Wake-on-LAN features and advertise those. Similarly, when configuring Wake-on-LAN on a per-port network interface, we make sure that we do not accept something the master network devices does not support. Finally, we need to maintain a bitmask of the ports enabled for Wake-on-LAN to prevent the suspend() callback from disabling a port that is used for waking up the system.
