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