31 Pointer to a \fBscsi_address\fR(9S) structure.
40 Pointer to a \fBscsi_pkt\fR(9S) structure.
46 The \fBtran_abort()\fR vector in the \fBscsi_hba_tran\fR(9S) structure must be
47 initialized during the HBA driver's \fBattach\fR(9E) to point to an HBA entry
48 point to be called when a target driver calls \fBscsi_abort\fR(9F).
51 \fBtran_abort()\fR should attempt to abort the command \fIpkt\fR that has been
52 transported to the HBA. If \fIpkt\fR is \fBNULL\fR, the HBA driver should
53 attempt to abort all outstanding packets for the target/logical unit addressed
57 Depending on the state of a particular command in the transport layer, the HBA
58 driver may not be able to abort the command.
61 While the abort is taking place, packets issued to the transported layer may or
65 For each packet successfully aborted, \fBtran_abort()\fR must set the

67 \fBOR'ed\fR with \fBSTAT_ABORTED\fR .
71 \fBtran_abort()\fR must return:
