New Revision: 277515
URL: https://svnweb.freebsd.org/changeset/base/277515
Log:
Fix SCSI status byte reporting on 4Gb and 8Gb Qlogic boards.
The newer boards don't have the response field that indicates
whether the SCSI status byte is present. You have to just look to
see whether it is non-zero.
The code was looking to see whether the sense length was valid
before propagating the SCSI status byte (and sense information) up
the stack. With a status like Reservation Conflict, there is no
sense information, only the SCSI status byte. So it wasn't getting
correctly returned.
isp.c:
In isp_intr(), if we are on a 2400 or 2500 type board and
get a response, look at the actual contents of the
SCSI status value and set the RQSF_GOT_STATUS flag
accordingly so that return any SCSI status value we get. The
RQSF_GOT_SENSE flag will get set later on if there is
actual sense information returned.
