[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.
