All packets passing through a switch of the 6185 family are currently all directed to the CPU port. This means that port bridging is software driven.
To enable hardware bridging for this switch family, we need to implement the port mapping operations, the FDB operations, and optionally the VLAN operations (for 802.1Q and VLAN filtering aware systems). However this family only has 256 FDBs indexed by 8-bit identifiers, opposed to 4096 FDBs with 12-bit identifiers for other families such as 6352. It also doesn't have dedicated FID registers for ATU and VTU operations. This patchset fixes these differences, and enable hardware bridging for 6185.
