Re: igmp group stopped

The word "stopped" indicates that timing out of this entry is not determined
by this expire timer. If the router is in INCLUDE mode for a group, then the
whole group entry will time out after the last source entry has timed out
(unless the mode is changed to EXCLUDE mode before it times out).
