Reflects the value of the operEdgePort parameter, as
defined by the operation of the Bridge Detection state
machine (Clause 18 of P802.1t). The value of this parameter
is used by a Designated Port in order to determine how
rapidly it may transition to the Forwarding Port State
(see 17.23, Port Role Transitions state machine).
The Bridge Detection state machine sets this parameter to
the value of adminEdgePort (P802.1t 18.1.3) on
initialization, and forces its value to FALSE if any BPDUs
are received on the Port.
