With remote wake, the firmware creates a TCP connection and sends some configurable data on it, until a special TCP data packet from the server is received that triggers a wakeup. The configuration is a bit tricky because it is based on packet pattern matching but this is hidden in the driver and the exposed API in cfg80211 is just based on the required TCP connection parameters.
