ath6kl: Multicast filter support in wow suspend and non-suspend
This patch enables all multicast packets in non suspend mode
and enable multicast filtering in wow suspend mode. This also
fixes a bug in multicast where the driver assumed disable
multicast-all command disabled/filtered all multicast
packets, which was wrong assumption, because firmware will
apply the programmed filter.
Multicast requirements
- Enable forward all multicast packets(no filtering) in
non suspend mode.
- Enable multicast filtering in wow suspend mode for both
AP and CLIENT.
