illumos DDI specific (illumos DDI).
After filling in scsi_pkt(9S) fields with packet completion
information, an HBA driver should call the scsi_hba_pkt_comp()
function. This function is the recommended way for an HBA driver to
signal completion of a scsi_pkt structure. Use is mandatory for HBA
drivers that use tran_setup_pkt(9E).
Calling the scsi_hba_pkt_comp() function allows SCSA to observe, and
possibly react to, the completion of a scsi_pkt request.
A call to the scsi_hba_pkt_comp() function will always result in a
call to the pkt_comp() callback function defined in scsi_pkt(9S).
This pkt_comp() callback may, however, occur after return from
scsi_hba_pkt_comp(), and may occur from a different thread executing
on a different CPU.
The scsi_hba_pkt_comp() function can be called from user, interrupt,
or kernel context.
