        So do u consider mandating definition of zero-window probes as defined
        in RFC793 as a bug in RFC1122?

        Or else r u saying this bug is introduced in linux to take care of
        faulty stacks existing in the world. zero-window probes as defined
        in RFC1122 is not buggy right?
