Chris Badura bad@bsd.de said the following:
So, I've looked at this.  I think the 29369 PR is not fine.  There are only
only 2 scsi tape firmware manufacturers and probably only 1 LTO firmware
vendor.  The driver should detect that the device is a LTO drive (maybe by
capacity as the other QIC_* drives too) and clear ST_2FM_AT_EOD in that
case too.

To be more correct the drive should determine this from the EOD and SOCF
fields in the device's Device Configuration Page which has been the standard
way since roughly 1991.  *sigh*

Frank, what do you think? Is that something you'd be interested doing?
