        or replacements for objects of the original, MIB-II, ifTable
        that were deprecated because the semantics of said objects
        have significantly changed.  This table also contains objects
        that were previously in the ifExtnsTable.

   ifStackTable
        This table contains objects that define the relationships
        among the sub-layers of an interface.

   ifTestTable
        This table contains objects that are used to perform tests on
        interfaces.  This table is a generic table.  The designers of
        media-specific MIBs must define exactly how this table
        applies to their specific MIB.

        This table replaces the interface test table defined in
        RFC1229 [7].  The significant change is the replacement of
        the ifExtnsTestCommunity (and ifExtnsTestContext which would
        also have been required for SNMPv2) and ifExtnsTestRequestId
        objects, by the new ifTestId, ifTestStatus, and ifTestOwner
        objects.

   ifRcvAddressTable
        This table contains objects that are used to define the
        media-level addresses which this interface will receive.
        This table is a generic table.  The designers of media-
        specific MIBs must define exactly how this table applies to
        their specific MIB.

               The definition of this textual convention with the
               addition of newly assigned values is published
               periodically by the IANA, in either the Assigned
               Numbers RFC, or some derivative of it specific to
               Internet Network Management number assignments.  (The
               latest arrangements can be obtained by contacting the
               IANA.)

               Requests for new values should be made to IANA via
               email ([e-mail]).

               The relationship between the assignment of ifType
               values and of OIDs to particular media-specific MIBs
               is solely the purview of IANA and is subject to change
               without notice.  Quite often, a media-specific MIB's
               OID-subtree assignment within MIB-II's 'transmission'
               subtree will be the same as its ifType value.
               However, in some circumstances this will not be the
               case, and implementors must not pre-assume any
               specific relationship between ifType values and
               transmission subtree OIDs."
