I started porting PPPd 2.4.5 to lwIP this week-end. With additional 
patchs fetched from Debian, as PPPd is a dead project since 2009.

I got some grey hair, I agree, but it works !

Well, it only works with PPPoE at the moment, because this is easy to 
test with the unix port. I still have to find a way to test PPPoS, which 
require a SIO somewhere, maybe I will do a unix SIO port, this seems 
easier than using a takes-minutes-to-flash-and-hard-to-debug uC.

However, it works, but this is not sufficient for lwIP, a lot of code is 
still using the Linux basement, and should be evicted before any patch.

I am going to push this port in production where I work, with a remote 
flash boot loader so that I will be able to fix all the bugs I added, 
being a very good bugs provider :-)

But the way, all the strangeness I found in the current PPPd port 
included in lwIP are fixed the way I thought in the latest PPPd, which 
is a good news !

Also, with PPPd 2.4.5, PPP + IPv6 support is on its way, as well as new 
authentification methods. And maybe we could add in the future L2TP 
support, allowing lwIP users to do PPP tunnels behing NAT using UDP as a 
transport protocol.
