Is there a standard scsi way to assign tag values?
Can I use the block layer helpers, or do those not work for scsi?

Which kernel? In 2.5 you can get the scsi mid layer to do it for you
(via the block layer helpers), by calling scsi_activate_tcq(scsi_device,
depth). See scsi_tcq.h and 53c700.c for a working example.

That's what I was looking for, thanks.
for 2.4, multiple people told me "yeah, you have to make up your own tag
values"
