Some ethernet controllers can hear themselves.

Some ethernet controllers are capable of hearing packets that they are
transmitting as they are being transmitted. If this is true, then
sending a packet to yourself is a good way to check whether the
ethernet is in good shape - it checks the transceiver and the ethernet
cable as well as the controller.
