I missed the definition for "valid" in 3.2. That resolves my confusion. >>> A TCP segment MUST >>> include at most one suboption whose high nibble is 0. >> >> Does this mean "A TCP SYN segment including the TCP-ENO option MUST..."? > > Yes. Would the following wording help: "A TCP segment MUST include at > most one ENO suboption whose high nibble is 0." Yes, that is more precise.
