  30.      The _llll______qqqq_tttt_oooo_pppp field is a pointer to the lowest write queue in the upper
  31.      stream.  In other words, it is the write queue of the multiplexing
  32.      driver.  If the link is persistent across closes of the driver, then this
  33.      field is set to _NNNN_UUUU_LLLL_LLLL.
  34.  
  35.      The _llll______qqqq_bbbb_oooo_tttt field is a pointer to the upper write queue in the lower
  36.      stream.  The lower stream is the stream being linked under the
  37.      multiplexor.  The topmost read and write queues in the lower stream are
  38.      given to the multiplexing driver to use for the lower half of its
  39.      multiplexor processing.  The _qqqq_iiii_nnnn_iiii_tttt(D4) structures associated with these
  40.      queues are those specified for the lower processing in the multiplexing
  41.      driver's _ssss_tttt_rrrr_eeee_aaaa_mmmm_tttt_aaaa_bbbb(D4) structure.
  42.  
  43.      The _llll______iiii_nnnn_dddd_eeee_xxxx field is a unique ID that identifies the multiplexing link in
  44.      the system.  The driver can use this as a key on which it can multiplex
  45.      or de-multiplex.
