It is currently unsupported.

The goal is to change the TTL in the IPv4 header and in the corresponding v6 option.

As discussed at the last meeting, the best for the sockopt is probably to propagate the info to all new subflows by default except there is a technical issue. If needed, BPF can be use to unset stuff.
