tested, and it does wake up on broadcasted and unicasted UDP magic packet, but
not any other kinds of packets. More specifically:

(Magic payload, UDP, IP dest link broadcast, eth dest broadcast) ->
wakes up on 'g' and 'b'

(Magic payload, UDP, IP dest unicast, eth dest unicast) ->
wakes up on 'g' and 'b'

(arp: eth broadcast) ->
does NOT wake up on 'b' as expected

Hmmm, maybe 'b' stands for IP broadcast and not eth broadcast? Let's see:
(ping broadcast: icmp,  IP dest broadcast, eth dest broadcast) ->
does NOT wake up on 'b'.

As best I can tell, the patch fixes the g case, but something's still broken 
for the other cases the device claims to support ('pumb').
