also part of 8925:
" If the server responds with the IPv6-Only Preferred option and the V6ONLY_WAIT timer is configured for the pool, the server MUST copy the configured value to the IPv6-Only Preferred option value field. Otherwise, it MUST set the field to zero."

in reply to Thomas Schäfer • • •If the IPv6-Only Preferred option returned by the server contains a value greater than or equal to MIN_V6ONLY_WAIT, the client SHOULD set the V6ONLY_WAIT timer to that value. Otherwise, the client SHOULD set the V6ONLY_WAIT timer to MIN_V6ONLY_WAIT.
