2015-03-29net: dsa: mv88e6xxx: Disable Message Port bit for CPU portGuenter Roeck
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.

2015-02-25net: dsa: bcm_sf2: add HW bridging supportFlorian Fainelli
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.

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 power on/off recommended procedure for the Single GPHY we have on our Starfighter 2 switch. 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.
