Module Name:    src
Committed By:   bouyer

Modified Files:
        src/sys/dev/scsipi: scsiconf.c

Log Message:
If the controller supports more than 256 commands per target,
clamp it to 256 (maximum number of tags in SCSI). Newer controllers
(such as mpii(4), and mfi(4) when fixed to announce tagged queuing support)
support more than 256 outstanding commands and don't use the scsi tag,
but at this time scsipi will always allocate a tag, and panic if a periph
tries to send more than 256 commands.
