Depending on the breakout mode of the physical ports the internal NFP
port number might differ from the actual physical port number. Prior to
this patch the physical port number was used when making configuration
changes to the physical ports (enable, admin up etc). After this change
the internal port number is now correctly used for configuration
changes.
