Hello,
In the same kind of issue, is there a way to stop the the tcpip_thread
cleanly ?

Yes, this is one of the known drawback of the PPP_INPROC_OWNTHREAD
feature, please use only PPP_INPROC_MULTITHREADED instead with your
own receive loop.
For information, I have removed the lwIP owned receive thread from
my ppp-new branch because it draws much more inconvenients for
(almost) no advantages.
