327    Multicast filtering rules work as follows:
328
329    The driver can filter multicast (v4 and/or v6) and broadcast packets when in
330    a power optimized mode (typically when screen goes off).
331
332    In order to prevent the driver from filtering the multicast/broadcast packets, we have to
333    add a DRIVER RXFILTER-ADD rule followed by DRIVER RXFILTER-START to make the rule effective
334
335    DRIVER RXFILTER-ADD Num
336        where Num = 0 - Unicast, 1 - Broadcast, 2 - Mutil4 or 3 - Multi6
337
338    and DRIVER RXFILTER-START
339
340    In order to stop the usage of these rules, we do
341
342    DRIVER RXFILTER-STOP
343    DRIVER RXFILTER-REMOVE Num
344        where Num is as described for RXFILTER-ADD
345
346    The  SETSUSPENDOPT driver command overrides the filtering rules
