ethtool says:
wol p|u|m|b|a|g|s|f|d...
Sets Wake-on-LAN options. Not all devices support this. The argument to this option is a
string of characters specifying which options to enable.
p Wake on PHY activity
u Wake on unicast messages
m Wake on multicast messages
b Wake on broadcast messages
a Wake on ARP
g Wake on MagicPacket™
s Enable SecureOn™ password for MagicPacket™
f Wake on filter(s)
d Disable (wake on nothing). This option
clears all previous options.
So why do we need a DT property?
