.SH WARNING
The \fBscsi_free_consistent_buf()\fR function will call \fBfreerbuf\fR(9F) to
free the \fBbuf\fR(9S) that was allocated before or during the call to
\fBscsi_alloc_consistent_buf\fR(9F).

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