DESCRIPTION

     scsi_free_consistent_buf() frees a buffer  header  and  con-
     sistent  data  buffer  that  was  previously allocated using

WARNING

     scsi_free_consistent_buf() will call  freerbuf(9F)  to  free
     the
      buf(9S) that was allocated before or  during  the  call  to
     scsi_alloc_consistent_buf(9F).

     If consistent memory is bound to  a  scsi_pkt(9S),  the  pkt
     should be destroyed before freeing the consistent memory.
