We are working on a modular router where it is possible to connect multiple switch cards and at most one SFP cage card to a router. Does the sfp/dsa driver support connecting SFP port to a DSA port? For example the Marvell 6390 switch has two SGMII ports and 8 1Gbps PHYs. One can then connect those 8 1Gbps PHYs to RJ-45 connectors, the first SGMII port to the CPU and the second SGMII port to SFP. I think this is currently not possible, but am not sure. Thanks.
