* net: dsa: mv88e6xxx: factorize MAC address settingVivien Didelot2016-05-09
| | | | | | | | | | | Some switch models have a dedicated register for Switch MAC/WoF/WoL. This register, when present, is used to indirectly set the switch MAC address, instead of a direct write to 3 global registers. Identify this feature and share a common mv88e6xxx_set_addr function.

| * net: dsa: mv88e6xxx: share the same default FDBVivien Didelot2016-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For hardware cross-chip bridging to work, user ports *and* DSA ports need to share a common address database, in order to switch a frame to the correct interconnected device. This is currently working for VLAN filtering aware systems, since Linux will implement a bridge group as a 802.1Q VLAN, which has its own FDB, including DSA and CPU links as members. However when the system doesn't support VLAN filtering, Linux only relies on the port-based VLAN to implement a bridge group. To fix hardware cross-chip bridging for such systems, set the same default address database 0 for user and DSA ports, instead of giving them all a different default database. Note that the bridging code prevents frames to egress between unbridged ports, and flushes FDB entries of a port when changing its STP state. Also note that the FID 0 is special and means "all" for ATU operations, but it's OK since it is used as a default forwarding address database. Fixes: 2db9ce1fd9a3 ("net: dsa: mv88e6xxx: assign default FDB to ports") Fixes: 466dfa077022 ("net: dsa: mv88e6xxx: assign dynamic FDB to bridges") Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | In multi-chip systems, DSA Tag ports must learn SA addresses in order to correctly switch frames between interconnected chips. This fixes cross-chip hardware bridging in a VLAN filtering aware system, because a bridge group gets implemented as an hardware 802.1Q VLAN and thus DSA and user ports share the same FDB.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Locking a port generates an hardware interrupt when a new SA address is received. This enables CPU directed learning, which is needed for 802.1X MAC authentication. To disable automatic learning on a port, the only configuration needed is to set its Port Association Vector to all zero. Clear PAV when SA learning should be disabled instead of locking a port.

| | | | | | | | Implement port_vlan_filtering in the driver to toggle the related port 802.1Q mode between DISABLED and SECURE, on user request. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* net: dsa: mv88e6xxx: remove reserved VLANsVivien Didelot2016-03-01
| | | | | | | | | | | | Now that ports isolation is correctly configured when joining or leaving a bridge, there is no need to rely on reserved VLANs to isolate unbridged ports anymore. Thus remove them, and disable 802.1Q on setup. This restores the expected behavior of hardware bridging for systems without 802.1Q or VLAN filtering enabled.

* net: dsa: mv88e6xxx: restore VLANTable map controlVivien Didelot2016-03-01
| | | | | | | | | | | | | | | | The In Chip Port Based VLAN Table contains bits used to restrict which output ports this input port can send frames to. With the VLAN filtering enabled, these tables work in conjunction with the VLAN Table Unit to allow egressing frames. In order to remove the current dependency to BRIDGE_VLAN_FILTERING for basic hardware bridging to work, it is necessary to restore a fine control of each port's VLANTable, on setup and when a port joins or leaves a bridge.
