Jan,
I'm very sorry for the long delay, too many critical issues in progress
here...
Well, I did enable (lets hope) everything, the linux scsi drivers are
apparently using. I've put debug printfs into the frontend driver,
which has lead to several commands like READ16. I did real tests using 2
LSI U320 scsi controllers with multipathing and an attached Eonstor
RaidArray + tests using the Ultrium LTO3 Autoloader + bacula.
Additionally, I enabled several other SCSI commands found
in other scsi drivers like "sr".
I don't quite understand why the original authors excluded so many
commands (thats what I state in my patch header)
and hence I included only what was needed. Excluding makes sense only
when emulation is needed but did not want to enable too much...
