NAME
     eisa_dma_stop - stop software-initiated DMA operation on a channel and
     release it

SYNOPSIS
     #include <sys/eisa.h>

     void eisa_dma_stop(vint_t adap, int chan);

   Arguments
     adap Bus adapter number (zero on an Indigo2).

     chan Channel on which the DMA operation is to be stopped.

DESCRIPTION
     eisa_dma_stop stops a software-initiated DMA operation in progress on the
     channel chan. The channel is then released and made available for other
     use.

     The caller must ensure that it is acting on behalf of the channel owner,
     and that it makes sense to release the channel. The caller must also
     ensure that the channel is in use for software-initiated DMA transfers
     and not hardware-initiated transfers.

   Return Values
     None

   Level
     Base or Interrupt
