Implement the Poll Sequence (initiate on reaching Up when the configured interval is lower than the slow-start one; respond to Poll with Final; terminate on Final) and apply DesiredMinTxInterval changes per RFC 5880 section 6.8.3, keeping the slow rate until the peer has acknowledged. Never set the Demand bit unless demand mode is active, clear the C bit (this implementation shares fate with the control plane), discard packets whose Length exceeds the received payload, and log effective timer changes.
