Log message:
	Improve the logic for handling handling multicast vifs if the MLD/IGMP
	receives notifications about network interface related changes:
	
	* If the vif's primary address is deleted or there are no more
	  addresses then stop the vif.
	
	* If the vif's primary address has changed then restart the vif.
	
	Note that the above changes might not work well in practice
	in case the kernel decides to do something on its own with
	the correponding multicast vif state inside the kernel itself.
	Another potential issue is if the kernel doesn't let the userland
	program to (re)join the same (IPv4) multicast group with the new
	IPv4 address as a handler (probably because of a kernel bug
	if the kernel still keeps multicast membership information
	about the old IP address inside the network interface driver).
