322    Multicast filtering rules work as follows:
323
324    The driver can filter multicast (v4 and/or v6) and broadcast packets when in
325    a power optimized mode (typically when screen goes off).
326
327    In order to prevent the driver from filtering the multicast/broadcast packets, we have to
328    add a DRIVER RXFILTER-ADD rule followed by DRIVER RXFILTER-START to make the rule effective
329
330    DRIVER RXFILTER-ADD Num
331        where Num = 0 - Unicast, 1 - Broadcast, 2 - Mutil4 or 3 - Multi6
332
333    and DRIVER RXFILTER-START
334
335    In order to stop the usage of these rules, we do
336
337    DRIVER RXFILTER-STOP
338    DRIVER RXFILTER-REMOVE Num
339        where Num is as described for RXFILTER-ADD
340
