[patch 3/7] s390: qeth multicast address registration fixed

From: Klaus Dieter Wacker <kdwacker@de.ibm.com>
	- when running in Layer2 mode we don't have to register
	  the multicast IP address but only group mac address.
	  Therefore for Layer 2 devices it is enough to go
	  through dev->mc_list list and register these entries.
