This object can be set by a management station when
it detects that there is a duplicate MAC address.
This object is OR'd with icfVgRptrDetectedDupAddress
to form the value of the 'D' bit in training response
frames on this port.
The purpose of this object is to provide a means for
network management software to inform an end station
that it is using a duplicate station address.
Setting this object does not affect the current state
of the link; the end station will not be informed of
the duplicate address until it retrains for some
reason. Note that regardless of its station address,
the end station will not be able to train
successfully until the network management software
has set this object back to 'false'. Although this
object exists on cascade ports, it does not perform
any function since this repeater is the initiator of
training on a cascade port.
