 Inferior brain on the receiver side, I guess ;-)

 The radio is connected to the host via the USB bus plus 1 wakeup line into
 the motherboard's embedded controller (EC). During suspend there is no way
 for the radio to wakeup the host via the USB bus.
 If a received frame meets the wakeup criteria, then the radio wakes up the
 host via the line to the EC.

 Maybe I am confused since the beginning of this thread because I don't get
 how a multicast frame will only wake up a subset of hosts (or in other
 words, how do you define which multicast group each subset listens to).
