There are standard operations to configure Wake-on-LAN (commands
ETHTOOL_{G,S}WOL, driver methods ethtool_ops::{get,set}_wol) and WOL
modes including MagicPacket.

If you want to implement a more sophisticated packet matching mode that
requires more details than struct ethtool_wolinfo, then you may need to
define new operations.
