* net: dsa: mv88e6xxx: remove all MACs when disabling a portVivien Didelot2015-09-151-1/+1
| | | | | | | | | When we're moving a port from Learning or Forwarding state to Disabled or Blocking or Listening state, remove all non-static MAC addresses mapped to this port in the entire set of databases, not only one.

* net: dsa: mv88e6xxx: remove addresses when a port leaves a VLANVivien Didelot2015-09-151-0/+29
| | | | | | | | | | | | | | Add a new _mv88e6xxx_atu_move function to prepare the ATU data register for the move operation. The ports vector will contain the source port and destination port of the Move operation. If the destination port is 0xF, the MAC addresses mapped to the source port are removed for the address database(s). Then add a _mv88e6xxx_atu_remove wrapper to remove the MAC addresses from a VLAN database that are mapped to a given port, when it leaves it.

* net: dsa: mv88e6xxx: rework ATU Flush operationVivien Didelot2015-09-152-13/+44
| | | | | | | | | | | | | | | | | | | These Marvell switches have 4 operations to flush or (re)move, all or only non-static MAC addresses, from the entire set of databases or from just a particular one. The value of the EntryState bits will determine if the operation is either a Flush (0x0) or a Move (0xF). When moving entries from one port to another, entries will be removed if the destination port is 0xF. This patch renames these operations for consistency, add a new generic _mv88e6xxx_atu_flush_move function, and change _mv88e6xxx_flush_fid to use it.

* net: dsa: bcm_sf2: Fix ageing conditions and operationFlorian Fainelli2015-09-091-4/+8
| | | | | | | | | | | | | | | | | | | The comparison check between cur_hw_state and hw_state is currently invalid because cur_hw_state is right shifted by G_MISTP_SHIFT, while hw_state is not, so we end-up comparing bits 2:0 with bits 7:5, which is going to cause an additional aging to occur. Fix this by not shifting cur_hw_state while reading it, but instead, mask the value with the appropriately shitfted bitmask. The other problem with the fast-ageing process is that we did not set the EN_AGE_DYNAMIC bit to request the ageing to occur for dynamically learned MAC addresses. Finally, write back 0 to the FAST_AGE_CTRL register to avoid leaving spurious bits sets from one operation to the other.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 7445E0 contains an ECO which disconnected the internal SF2 pseudo-PHY which was known to conflict with the external pseudo-PHY of BCM53125 switches. This motivated the need to utilize the internal SF2 MDIO controller via indirect register reads/writes to control external Broadcom switches due to this address conflict (both responded at address 30d). For 7445E0, the internal pseudo-PHY of the SF2 switch got disconnected, and as a consequence this prevents the internal SF2 MDIO bus controller from reading data (reads back everything as 0) since the MDI line is tied low. Fix this by making the indirect register reads and writes conditional to 7445D0, on 7445E0 we can utilize the SWITCH_MDIO controller (backed by mdio-unimac and not the DSA created slave MII bus). We utilize of_machine_is_compatible() here since this is the only way for use to differentiate between these two chips in a way that does not violate layers or becomes (too) vendor-specific.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mv88e6xxx_priv_state structure contains an fid_mask, where 1 means the FID is free to use, 0 means the FID is in use. This patch fixes the bit clear in mv88e6xxx_leave_bridge() when assigning a new FID to a port. Example scenario: I have 7 ports, port 5 is CPU, port 6 is unused (no PHY). After setting the ports 0, 1 and 2 in bridge br0, and ports 3 and 4 in bridge br1, I have the following fid_mask: 0b111110010110 (0xf96). Indeed, br0 uses FID 0, and br1 uses FID 3. After setting nomaster for port 0, I get the wrong fid_mask: 0b10 (0x2). With this patch we correctly get 0b111110010100 (0xf94), meaning port 0 uses FID 1, br0 uses FID 0, and br1 uses FID 3.
