Other Tag Control Information (TCI) are valid, but not supported by the driver. So this patch changes the returning code from igc_add_ ethtool_nfc_entry() to -EOPNOTSUPP in order to provide more meaningful information on why the function failed. It also adds a debug messages to give the user a hint about what went wrong with the NFC setup.
