        "Updated to include support for 10 Gb/sec
      interfaces.  This resulted in the following
      revisions:
      
      - Updated dot3StatsAlignmentErrors and
        dot3StatsSymbolErrors DESCRIPTIONs to
        reflect behaviour at 10 Gb/s
      - Added dot3StatsRateControlAbility and
        dot3RateControlStatus for management
        of the Rate Control function in 10 Gb/s
        WAN applications
      - Added 64-bit versions of all counters
        that are used on high-speed ethernet
        interfaces
      - Added object groups to contain the new
        objects
      - Deprecated etherStatsBaseGroup and
        split into etherStatsBaseGroup2 and
        etherStatsHalfDuplexGroup, so that
        interfaces which can only operate at
        full-duplex do not need to implement
        half-duplex-only statistics
      - Deprecated dot3Compliance and replaced
        it with dot3Compliance2, which includes
        the compliance information for the new
        object groups
      
      In addition, the dot3Tests and dot3Errors
      object identities have been deprecated,
      since there is no longer a standard method
      for using them.
