> +PTO period being set to twice its current value. The PTO backoff is reset upon
+receiving an acknowledgement, except when a client receives an acknowledgment
+from a server prior to the server validating the client address. A client
+keeps increasing the PTO backoff until the server's address validation
+completes to ensure the client's PTO timer is not set too aggressively
+when the server is slow in responding with handshake data.
