I happened to notice that a system with an NVidia NIC using the
forcedeth driver won't wake-on-LAN if the interface was in promiscuous
mode when you power off. By experiment, it looks like
the hardware needs to have NvRegPacketFilterFlags set to
NVREG_PFF_ALWAYS|NVREG_PFF_MYADDR (i.e., receive unicast packets to my
address) in order for WoL to work.

to insert a signed-off-by line with his name on it, though.
