Facebook designed the Tioga Pass server and we use the NC-SI path on
that server.  Since the server was designed for OCP, we recognize NC-SI
isn't always the preferred path for everyone, so we included the other
interface even thought we don't use it ourselves.

There was work at one point to qualify the second interface, but that
work was done on an old kernel branch and never sent upstream.  Since the
faraday driver had a large rewrite, I would be surprised if this patch
applies cleanly to the 5.x series, but here it is:
