If there is no interface, that supports multicasting, with an IPv6 
address, then the test will not execute the particular IPv6 multicasting 
scenario. That is fine, the IPv6 portion of the test is effectively 
skipped, since it cannot be tested on the particular platform. ( One 
could separate IPv4 from IPv6 in this test, and rather return a jtreg 
skipped status if a suitable interface with IPv6 is not found. But is 
does not seem worth while. )
