This class represents state data.
A table of descriptive and status information
about the MAC Control sublayer on the
ethernet-like interfaces attached to a
particular system. There will be one row in
this table for each ethernet-like interface in
the system which implements the MAC Control
sublayer. If some, but not all, of the
ethernet-like interfaces in the system implement
the MAC Control sublayer, there will be fewer
rows in this table than in the dot3StatsTable.
