[SCSI] iscsi: add target discvery event to transport class
Patch from david.somayajulu@qlogic.com: Add target discovery event. We may have a setup where the iscsi traffic is on a different netowrk than the other network traffic. In this case we will want to do discovery though the iscsi card. This patch adds a event to the transport class that can be used by hw iscsi cards that support this.
