So I assume you're getting traffic on the other port and it doesn't
complain about "unqualified module"?  Does the problem move if you
swap the cables?  The usual problem here is a QSFP connector that
isn't compatible with the NIC.  I don't have a pointer handy to the
official list, but you should be able to get that from your NIC
supplier.
