5. Tagged command queueing

Some scsi devices donnot support properly tagged command queuing.
A safe configuration can be to not enable tagged command queuing support at 
boot-up, and to enable support of it with the control command "settags" 
described further in this text.

Once you are sure that all your devices support properly tagged command queuing,
you can enable it by default with the CONFIG_SCSI_NCR53C8XX_TAGGED_QUEUE 
configuration option.
