This is needed in order to detect if the timestamp option appears more than once in a packet, to remove the option if the packet is fragmented, etc. My previous change neglected to store the option location when the router addresses were prespecified and Pointer > Length. But now the option location is also stored when Flag is an unrecognized value, to ensure these option handling behaviors are still performed.
