Hi Thomas,

> how does this happen and why should this be?
this might has been confusing, because this was the last mail sent from
Github notifications to this mailing list (instead of the new one:
notifications at riot-os.org).

Anyway, we discovered this bug during the 6LoWPAN plugtest today. When
selecting a source address, sixlowip calls a function to find the biggest
match between destination address and addresses assigned to its own interface.
However, this function currently also chooses multicast addresses assigned to
the interface, which is not intended.

The good thing about Apple jokes is that everyone think they are new, funny and awesome, even if you just stole them.
