The related options are clubbed as a bit map, each bit means something within 
an option.
I am trying to give few examples for each option,

+             FLASH_TGT_OPTIONS,
                This is an IPv6 target
                This is a discovery target (send target)

                Data Digest is enabled
                Header Digest is enabled

+             FLASH_TGT_TCP_OPTIONS,
                Disable TCP Scale Window

+             FLASH_TGT_IP_OPTIONS,
                Disable Fragmentation

Yes, this approach can setup a discovery portal, the way you tell the 
difference is by looking at the FLASH_TGT_OPTIONS.

Do let us know how to proceed?
