2.4 Wake-up frame
A Wake-up frame is a special data packet containing the Ethernet address of the remote network card. Somewhere in this frame should exist a byte stream (magic sequence) composed by, at the least, 16 times the repetition of the Ethernet address and preceded by a synchronization stream of 6 bytes of FFh.
If the Ethernet address of a target computer is 01:02:03:04:05:06 (6 bytes), then the LAN controller of that machine should be looking for the following sequence
inside the frame.
