Just FYI, I should have mentioned this earlier, I have observed the mptcp.org
kernel sending 32-bit DSS ack-only in the same header as final MP_CAPABLE ACK
so this statement isn't completely true.
Thank you for the info.
It looks like a .org bug to me ?!? the sender should not send DSS
before receiving the MP_CAPABLE ack, and the client should not send ack
before receving a DSS ?!?
Back to this series, do you prefer I'll revert to the existing checks?
