forcedeth: use unicast receive mode for WoL
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. Jeff Garzik writes: "NVIDIA says the patch looks OK." I didn't venture to insert a signed-off-by line with his name on it, though.
