Leaving this as draft for a moment as I would like to try accessing more PHY registers to test PHY features if I get a chance before leaving (though I am relatively confident if we can access some PHY registers then the rest should be no different) |

Marking this as ready for review as I am happy with it - however clang is about the smoketest and I don't have the time or the knowledge of C to address this. As far as I can tell it's only stylistic issues (the test passes fine after all) |
