* net: dsa: mv88e6xxx: Fix opps when adding vlan bridgeAndrew Lunn2016-12-161-0/+6
| | | | | | | | | | | | A port is not necessarily assigned to a netdev. And a port does not need to be a member of a bridge. So when iterating over all ports, check before using the netdev and bridge_dev for a port. Otherwise we dereference a NULL pointer.

* net: dsa: mv88e6xxx: add PPU operationsVivien Didelot2016-12-064-74/+81
| | | | | | | | | | | Some Marvell chips can enable/disable the PPU on demand. This is needed to access the PHY registers when there is no indirection mechanism. Add two new ppu_enable and ppu_disable ops to describe this and finally get rid of the MV88E6XXX_FLAG_PPU* flags.

* net: dsa: mv88e6xxx: add a soft reset operationVivien Didelot2016-12-064-40/+172
| | | | | | | | | | | | | | | Marvell chips have different way to issue a software reset. Old chips (such as 88E6060) have a reset bit in an ATU control register. Newer chips moved this bit in a Global control register. Chips with controllable PPU should reset the PPU when resetting the switch. Add a new reset operation to implement these differences and introduce a mv88e6xxx_software_reset() helper to wrap it conveniently.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All conflicts were simple overlapping changes except perhaps for the Thunder driver. That driver has a change_mtu method explicitly for sending a message to the hardware. If that fails it returns an error. Normally a driver doesn't need an ndo_change_mtu method becuase those are usually just range changes, which are now handled generically. But since this extra operation is needed in the Thunder driver, it has to stay. However, if the message send fails we have to restore the original MTU before the change because the entire call chain expects that if an error is thrown by ndo_change_mtu then the MTU did not change. Therefore code is added to nicvf_change_mtu to remember the original MTU, and to restore it upon nicvf_update_hw_max_frs() failue. Signed-off-by: David S. Miller <davem@davemloft.net>
| * net: dsa: b53: Fix VLAN usage and how we treat CPU portFlorian Fainelli2016-11-161-12/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently have a fundamental problem in how we treat the CPU port and its VLAN membership. As soon as a second VLAN is configured to be untagged, the CPU automatically becomes untagged for that VLAN as well, and yet, we don't gracefully make sure that the CPU becomes tagged in the other VLANs it could be a member of. This results in only one VLAN being effectively usable from the CPU's perspective. Instead of having some pretty complex logic which tries to maintain the CPU port's default VLAN and its untagged properties, just do something very simple which consists in neither altering the CPU port's PVID settings, nor its untagged settings: - whenever a VLAN is added, the CPU is automatically a member of this VLAN group, as a tagged member - PVID settings for downstream ports do not alter the CPU port's PVID since it now is part of all VLANs in the system This means that a typical example where e.g: LAN ports are in VLAN1, and WAN port is in VLAN2, now require having two VLAN interfaces for the host to properly terminate and send traffic from/to.

| | | | | | | | | | | | | | | | | | | | | | Most of the chips will have a port register control bits to force the port's link up, down, or let normal link detection occurs. Implement such operation to use it later when setting duplex, etc. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.
