> Changes in v2:
...
> When syn-cookies are used the SYN?ACK never contains a MPTCP option,
> because the code path that creates a request socket based on a valid
> cookie ACK lacks the needed changes to construct MPTCP request sockets.
>
> After this series, if SYN carries MP_CAPABLE option, the option is not
> cleared anymore and request socket will be reconstructed using the
> MP_CAPABLE option data that is re-sent with the ACK.
>
> This means that no additional state gets encoded into the syn cookie or
> the TCP timestamp.
...
Series applied, thanks Florian.
