Change the sa(4) driver to check for long position support on
SCSI-2 devices. Some older tape devices claim to be SCSI-2, but actually do support long position information. (Long position information includes the current file mark.) For example, the COMPAQ SuperDLT1. So we now only disable the check on SCSI-1 and older devices. sys/cam/scsi/scsi_sa.c: In saregister(), only disable fetching long position information on SCSI-1 and older drives. Update the comment to explain why. Confirmed by: dvl Sponsored by: Spectra Logic MFC after: 3 weeks
