Yes, see my comment about the ethtool .get_fec_stats. Maybe it is
there, hidden amongst all the code, but it is not obvious.

If you do want to stay in tree, may i suggest you move all your
statistics in your debugfs to official kernel APIs, and then remove
them from debugfs. This might require you work with the community to
extend the current APIs, which is the synergy thing Jakub is taking
about.
