Since there is no such thing as multicast on wifi, mobile devices drop 4 out of 5 packets send to the IPv6 all-nodes-multicast group on the baseband to safe battery.
TIL at #IETF105:
A: I propose we send an unsolicited neighbour advertisement to the all-*routers*-multicast group to speed up neighbour discovery on joining a link
B: Hang on, that might drain your battery real fast, I think we only drop all-nodes packets, not all-routers.
