I have used lwIP's PPP but am not sure what you mean by "PPP driver from
lwIP".

Do you need to use PPP-over-serial or PPP-over-Ethernet?


I used PPPoS for which I had to:

1. implement the serial IO interface defined in sio.h (see reference
implementations in contrib module)

2. use the PPP APIs defined in ppp.h to establish, manage, and terminate
a PPP link.


Take into consideration that:

1. as of lwIP 1.4.0 rc1, the APIs in ppp.h are not protected, i.e they
should be called from the tcpip thread context.

2. IMO, not all the APIs in ppp.h are actually public....


HTH,

Yoav.
