| |
Map the IPv6 header's destination multicast address to an ethernet source address instead of the MLD queries multicast address.
For instance for a general MLD query (multicast address in the MLD query set to ::), this would wrongly be mapped to 33:33:00:00:00:00, although an MLD queries destination MAC should always be 33:33:00:00:00:01 which matches the IPv6 header's multicast destination ff02::1.
