@@ -51,6 +51,8 @@ GCE does not provide preconfigured Fedora 21 image, so I set up the iSCSI target
 
 Once you have installed iSCSI initiator and new Kubernetes, you can create a pod based on the example *iscsi.json*. In the pod JSON, you need to provide *targetPortal* (the iSCSI target's **IP** address and *port* if not the default port 3260), target's *iqn*, *lun*, and the type of the filesystem that has been created on the lun, and *readOnly* boolean. No initiator information is required.
 
+If you want to use an iSCSI offload card or other open-iscsi transports besides tcp, setup an iSCSI interface and provide *iscsiInterface* in the pod JSON. The default name for an iscsi iface (open-iscsi parameter iface.iscsi\_ifacename) is in the format transport\_name.hwaddress when generated by iscsiadm. See [open-iscsi](http://www.open-iscsi.org/docs/README) or [openstack](http://docs.openstack.org/kilo/config-reference/content/iscsi-iface-config.html) for detailed configuration information.
+
 **Note:** If you have followed the instructions in the links above you
 may have partitioned the device, the iSCSI volume plugin does not
 currently support partitions so format the device as one partition.
