There is at least one obvious mistake here, but I'm pretty sure that's
not what fail here. You are calling sys_timeout/sys_untimout functions
outside the lwIP core thread, doing that is not thread safe. Other than
that it looks pretty well engineered, you are using pppos_input_tcpip
and so on, which is the right thing to do in your case.
I bet you are using the Socket or Netconn API in your task handling the
TCP session, which is right either.
