The tran_abort(9E) entry point for a SCSI HBA driver is called to abort any commands that are currently in transport for a particular target. This entry point is called when a target driver calls scsi_abort(9F).
The tran_abort() entry point should attempt to abort the command denoted by the pkt parameter. If the pkt parameter is NULL, tran_abort() should attempt to abort all outstanding commands in the transport layer for the particular target or logical unit.
Each command successfully aborted must be marked with pkt_reason CMD_ABORTED and pkt_statistics OR'd with STAT_ABORTED.
