Description (partial)

When a router with static MLD configurations receives MLD query,
it sends MLD reports followed by one ICMPv6 packet with unknown
type and code (type=0, code=0).
This is observed on C7600 router with 1200 static MLD users.
It can happen only at the first burst of MLD reports, for example,
when MLD interface becomes up.
