NAME
     scsi_free_consistent_buf - free a previously allocated  SCSI
     DMA I/O buffer

SYNOPSIS
     #include 



     void scsi_free_consistent_buf(struct buf *bp);


INTERFACE LEVEL
     Solaris DDI specific (Solaris DDI).

PARAMETERS
     bp    Pointer to the buf(9S) structure.


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

CONTEXT
     The scsi_free_consistent_buf() function can be  called  from
     user, interrupt, or kernel context.

SEE ALSO

     Writing Device Drivers

WARNING
     The   scsi_free_consistent_buf()    function    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.
