It's hard to write good multicast tests that don't require any 
configuration. All we can do is filter the "obvious" cases (such as 
interface that aren't up or don't support multicast). For these pseudo 
interface then it's very possible/likely that they will be plumbed with 
IPv4 or IPv6 address, in which case these tests will exercise them. For 
default setups where the interface appears to be plumbed with 0.0.0.0 
then it's okay/safe to ignore the interface. Any further probing would 
require additional support in the API or in the test suite.
