The MIB module for managing the new Ethernet OAM features
introduced by the Ethernet in the First Mile taskforce (IEEE
802.3ah).  The functionality presented here is based on IEEE
802.3ah [802.3ah], released in October, 2004.  [802.3ah] was
prepared as an addendum to the standing version of IEEE 802.3
[802.3-2002].  Since then, [802.3ah] has been
merged into the base IEEE 802.3 specification in [802.3-2005].

In particular, this MIB focuses on the new OAM functions
introduced in Clause 57 of [802.3ah].  The OAM functionality
of Clause 57 is controlled by new management attributes
introduced in Clause 30 of [802.3ah].  The OAM functions are
not specific to any particular Ethernet physical layer, and
can be generically applied to any Ethernet interface of
[802.3-2002].

An Ethernet OAM protocol data unit is a valid Ethernet frame
with a destination MAC address equal to the reserved MAC
address for Slow Protocols (See 43B of [802.3ah]), a
lengthOrType field equal to the reserved type for Slow
Protocols, and a Slow Protocols subtype equal to that of the
subtype reserved for Ethernet OAM.  OAMPDU is used throughout
this document as an abbreviation for Ethernet OAM protocol
data unit.
