Getting a SLAAC address takes a little while because the kernel must complete Duplicate Address Detection (DAD) before marking the address as ready. In several places we have an explicit 'sleep 2' to wait for that to complete. Fixed length delays are never a great idea, although this one is pretty solid. Still, it would be better to explicitly wait for DAD to complete in case of long delays (which might happen on slow emulated hosts, or with heavy load), and to speed the tests up if DAD completes quicker. Replace the fixed sleeps with a loop waiting for DAD to complete. We do this by looping waiting for all tentative addresses to disappear.
