Comment:

 I confirmed experimentally on a quiet network that all multicast packets
 were waking up the 8787 system, even when the system did not have that
 particular multicast address assigned.

 Fixed in arm-3.5 84c2bb7effacced073495e823270e6d6323aa3e0. mwifiex was
 setting the 'wakeup on all multicast' bit rather than just programming the
 selective multicast address list defined by the upper layers.
