The iSCSI Driver provides a host with the ability to access storage
through an IP network. The driver uses the iSCSI protocol to transport
SCSI requests and responses over a TCP/IP network between the host
(the "initiator") and "targets". Architecturally, the iSCSI driver
combines with the host's TCP/IP stack, network drivers, and Network
Interface Card (NIC) to provide the same functions as a SCSI or a
Fibre Channel (FC) adapter driver with a Host Bus Adapter (HBA).
To compile this driver as a module, choose M here: the
module will be called iscsi_tcp.
The userspace component needed to initialize the driver, documentation,
and sample configuration files can be found here:
