4	Description:
5			This file contains the enumerated host ID for the Intel
6			SCU controller. The Intel(R) C600 Series Chipset SATA/SAS
7			Storage Control Unit embeds up to two 4-port controllers in
8			a single PCI device.  The controllers are enumerated in order
9			which usually means the lowest number scsi_host corresponds
10			with the first controller, but this association is not
11			guaranteed.  The 'isci_id' attribute unambiguously identifies
12			the controller index: '0' for the first controller,
13			'1' for the second.
