Description

cxgbe(4): Do not request an FEC that is invalid for the requested speed.

This eliminates error messages like this from the driver when running at
50Gbps with 100G cables:
[3726] cc0: l1cfg failed: 71
[4407] cc0: l1cfg failed: 71

Note that link comes up anyway with or without this change.
