[...] So my questions are: is it possible to the firmware report a
wrong port type like
that? Is it somehow configurable by sysadmin (via fw update, ..), can
we flip that byte
or is it a manufacturing issue?

For completeness,

As it happens the customer had the HP Infinband Enablement Kit (614841-B21) installed at jumper location 53 (J53) of the motherboard, which makes the QSFP port of the S390s' NC543i interface an Infiniband interface rather than a 10gbE interface. Removing this allowed the port to be brought-up as 10GbE just fine.

Interesting that it worked as 10GbE even with InifiniBand Enablement Kit on it, so the port was just advertised, but not forced, as InfiniBand. Or something like that.

Thanks,
Marcelo.
