This class implements a tag that carries socket ancillary data to the socket interface. This is used like socket option of IP_PKTINFO/IPV6_PKTINFO in RFC 3542
This tag in the send direction is presently not enabled but we would accept a patch along those lines in the future. To include the nexthop in the send direction would increase the size of the tag beyond 20 bytes, so in that case, we recommend that an additional tag be used to carry the IPv6 next hop address.

This method is typically implemented by ns3::Object::GetInstanceTypeId but some classes which derive from ns3::ObjectBase directly have to implement it themselves.
