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?
