We can see there is a lot of code being deleted here, yet you are
adding support for stats. It would be good to explain in the commit
message what is really happening here.

+	DEFINE_STATS(rmon_collisions, EtherStatsCollisions, u32),
+	DEFINE_STATS(rmon_crc_align_errors, EtherStatsCRCAlignErrors, u32),
+	DEFINE_STATS(rmon_under_size_packets, EtherStatsUndersizePkts, u32),
+	DEFINE_STATS(rmon_fragments, EtherStatsFragments, u32),
+	DEFINE_STATS(rmon_jabbers, EtherStatsJabbers, u32),

Please report the standard RMON statistics via ethtool_rmon_stats. The
unstructured ethtool -S without groups should be used for statistics
which do not fit any of the well defined groups.
