The I225 controller supports Rx queue assignment based on VLAN priority only. 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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
