Subject: Is it currently possible to connect SFP to dsa port?
Date: Tue, 7 Aug 2018 21:00:23 +0200	[thread overview]
Message-ID: <20180807210023.0dc3d498@nic.cz> (raw)

Hello,

I have a question regarding DSA/SFP code.

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.

Marek Behun
