On my Ultra 1/170E, this fix enabled FAS to recognize 16 targets, not 8 
targets.
I tested with 6 additional SCSI HDDs with SCSI ID 9, 10, 11, 12, 13, 14.
I intended flags for esp driver for FAS to work as

    bits 0-7:   disable disconnect/rselect for SCSI target 0-7
    bits 8-15:  disable synchronous negotiation for SCSI target 0-7
    bits 16-23: disable disconnect/rselect for SCSI target 8-15
    bits 24-31: disable synchronous negotiation for SCSI target 8-15

However, since bit 16-23 is used to disable tagged queuing for SCSI target 
0-7,
this is ad-hoc approach.

I also sent it as a send-pr.
