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: |
