This 18 bit field is used to indicate the result of
  training.  It contains two bits which indicate if
  error-free training frames have been received, and it
  also contains the 16 bits of the most recent valid
  training response frame on the port.

      V:   Valid: set when at least one error-free
           training frame has been received.  Indicates
           the 16 training configuration bits in
           icfVgPortLastTrainConfig and
           icfVgPortTrainingResult contain valid
           information.  This bit is cleared when
           icfVgPortStatus transitions to the 
           'inactive' or 'training' state.
      G:   LinkGood: indicates the link hardware is OK.
           Set if 24 consecutive error-free training
           packets have been received.  Cleared when a
           training packet with errors is received, and
           when icfVgPortStatus transitions to the
           'inactive' or 'training' state.
      vvv: The version of the 802.12 training protocol
           with which the training responder is
           compliant
      D:   0  = no duplicate address has been detected
           1  = duplicate address has been detected
      C:   0  = the requested configuration is
                compatible with the port
           1  = the requested configuration is not
                compatible with the port.  The FF, PP
                and R bits indicate the configuration
                which would be allowed (providing 
                N = 0).
      N:   0  = access will be allowed, providing the
                configuration is compatible (C = 0).
           1  = access not allowed because of security
                restrictions
      FF:  00 = frameType88023 will be used
           01 = frameType88025 will be used
           10 = reserved
           11 = reserved
      PP:  00 = singleAddressMode will be used
           01 = promiscuousMode will be used
           10 = reserved
           11 = reserved
      R:   0  = requested access as an end node is
                allowed
           1  = requested access as a repeater is
                allowed

  If the port is in training, a management station can
  examine this object to see if any training packets
  have been passed successfully.  If there have been
  any good training packets, the Valid bit will be set
  and the management station can examine the 16
  training response bits to see if there is a duplicate
  address, configuration, or security problem.

  Note that on a repeater local port, this repeater
  generates the training response bits, while on the
  cascade port, the higher level repeater originated
  the training response bits.
