SFP connectors, RX framer errors

When running a custom DPDK test application on the HoneyComb Lx2 using the default DTB, we are seeing RX framer errors being reported from the DPMACs (observed from restool). We currently are using a CAB-10GSFP-P3M and noticed that https://solidrun.atlassian.net/wiki/spaces/developer/pages/287212203/SFP+Modules recommends using CAB-10GSFP-P1M.

Do you think the use of CAB-10GSFP-P3M could be causing the framer errors and that we should purchase the modules listed on the page? Or is there something in the DPAA2 configuration we should change based on what we are currently using?

I wouldn’t expect to see any framer errors given we have run the same test using NXP reference design boards (rev 1), and I’ve never seen RX framer errors there.

I checked with someone else on our team - the 3 meter cable could certainly explain why we’re seeing the RX framer errors. We’ll try to 1 meter cable and see if that resolves the issue.
