Accelerating open-iSCSI Initiator

The following steps need to be taken to accelerate the open-iSCSI initiator:
Configuring interface (iface) file
Create the file automatically by loading cxgb4i driver and then executing the following
command:
[root@host~]# iscsiadm -m iface
Alternatively, you can create an interface file located under iface directory for the new transport
class cxgb4i in the following format:
iface.iscsi_ifacename = <iface file name>
iface.hwaddress = <MAC address>
iface.transport_name = cxgb4i
iface.net_ifacename = <ethX>
iface.ipaddress = <iscsi ip address>
Here,
iface.iscsi_ifacename : Interface file in
iface.hwaddress
iface.transport_name
iface.net_ifacename
iface.ipaddress
Example:
iface.iscsi_ifacename = cxgb4i.00:07:43:04:5b:da
iface.hwaddress = 00:07:43:04:5b:da
iface.transport_name = cxgb4i
iface.net_ifacename = eth3
iface.ipaddress = 102.2.2.137
Chelsio Unified Wire for Linux
/etc/iscsi/ifaces/
: MAC address of the Chelsio interface via which iSCSI traffic will be
running.
: Transport name, which is cxgb4i.
: Chelsio interface via which iSCSI traffic will be running.
: IP address which is assigned to the interface.
