Follow-up Comment #2, bug #50694 (project lwip):

yes, i set TCP_OVERSIZE to TCP_MSS. if you set it as 0, it will check fail
when lwip init. 
Under this case, When last unsent have some space, and re-transmission it. the
unsent_oversize will reset as 0. After that, The App send data again will
enter concat_p allocate buffer. Then, it can't ensure TX single pbuf.
