That multicast indicates IP multicast (which is different from IB
multicast). IB multicast is needed for IP multicast but also IP unicast
to emulate the broadcast network on a LAN.

I was asking about if ifconfig showed UP:
ib0       Link encap:UNSPEC  HWaddr 00-00-04-05-FE-80-00-00-00-00-00-00-00-00-00-00  
          inet addr:192.168.0.11  Bcast:192.168.0.255  Mask:255.255.255.0
          inet6 addr: fe80::208:f104:396:55a/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:2044  Metric:1
