Narsimhulu Musini c8806b6c9e snic: driver for Cisco SCSI HBA
Cisco has developed a new PCI HBA interface called sNIC, which stands for
SCSI NIC. This is a new storage feature supported on specialized network
adapter. The new PCI function provides a uniform host interface and abstracts
backend storage.
