DESCRIPTION
     The  scsifreeconsistentbuf()  function  frees  a   buffer
     header  and consistent data buffer that was previously allo-
     cated using scsiallocconsistentbuf(9F).

     user, interrupt, or kernel context.

WARNING
     The   scsifreeconsistentbuf()    function    will    call
     freerbuf(9F)  to  free the buf(9S) that was allocated before
     or during the call to scsiallocconsistentbuf(9F).


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