I already started to implement other diagnostic features supported by the
TI DP83TG720 PHY. For example following can be implemented too:
6.3 Link quality – start-up time and link losses (LQ)
6.3.1 Link training time (LTT)
6.3.2 Local receiver time (LRT)
6.3.3 Remote receiver time (RRT)
6.3.4 Link Failures and Losses (LFL)
6.3.5 Communication ready status (COM)
6.4 Polarity Detection and Correction (POL)
6.4.1 Polarity Detection (DET)
6.4.2 Polarity Correction (COR)

What is the best way to proceed with them? Export them over phy-statistics
interface or extending the netlink interface?

Regards,
Oleksij
