Yeah, will need :-)

PPPd design, especially for the old 2.3.11, used in lwIP, is designed to 
run as a heavy process (a daemon), and do not care much about what is 
going on at the end of the PPP session, which stops the pppd process in 
almost all cases.

PPPd 2.4.5, with the requirements of the ML-PPP support, seems to handle 
much nicely what to do in the "lost channel" case. Anyway, if it still 
does not, we will fix that.


Currently, using the current lwIP PPP, I have to reset my uC at the end 
of the PPPoE session, else I get into deep troubles. Probably with 
reasons close to those you have with PPPoS.

I do not want to find bugs in PPPd 2.3.11 while I am porting the latest, 
that would be ridiculous.
