Well, several more really: two for the source address, two for the router
address, etc.

Doing that would probably also allow you to avoid using proto_item_set_text()
in decode_mcast_vpn_nlri() (assuming you set up the hf's correctly).

One more comment: the call to tvb_length_remaining() should probably be
tvb_reported_length_remaining().
