So...
the packet is obviously pre-processed in some way by the receiver chip and the fact it's a multicast packet which requires further processing is sufficient then for the receiver to wake the processor... which is fine for battery powered mobiles, but what about mains powered WiFi devices that aren't so bothered about power budgets? Do we then get into the realm of segregated multicasts, such that devices on battery listen on one 'multicast sub-net' and those on mains listen to another? Or is it easier just to redesign the mobile with either a smarter wifi chip that can process the RA itself, or one that just ignores multicasts altogether?
