Implement statistics for the PHY chips. Statistics are hold in
64-bit counters that wrap on overflow. They are collecte once per second from the chips. Currently they can be retrieved via a sysctl phy_stats. A write of an arbitrary value to the sysctl atomically retrieves the statistics and clears them.
