Test passed

This test verifies that the server is validating the client address using the Client Address Validation Procedure and does not send more than three times the amount of data sent by the test. The test sends an Initial packet and then intentionally does not reply to any packet received. After 3 seconds of inactivity during which no violation has been observed, the test issues ACKs to the received packets and completes the handshake.
