Hi,

We are having some issues with getting some CWDM optics to work with a BCM57840 
(Supermicro AOC-STG-B4S) NIC. All the SFPs we have are 1000Base-lx, but we are 
only able to get the 1310nm ones to work. When we connect the 1310nm SFPs dmesg 
says they are connected with 1G speed, but ifconfig says 10Gbase-SR. When we 
connect any of the other SFPs we get no info in dmesg and ifconfig says no 
carrier if we try to bring up the interface.

Do you have any suggestions for how we can try to figure out this does not work?
