This is kind of unusual, since our PPP stack only supports PPP client 
the IP address is usually given by the server. If you really need this 
we can add macro to set the necessary field in the PPP

It mostly depends on which lower level protocol you wish to use, PPPoS, 
PPPoE or PPPoL2TP, I am sure I already provided hints on this list which 
should be on the list archive.

Anyway, this isn't hard, the API is fully documented in headers and 
should be explanatory enough to give you the way to proceed.

If you really need an example, you can checkout the ppp-new branch of 
the contrib Git repository, it contains my quick'n'dirty source code I 
use to test the ppp-new branch in "lwip-contrib/ports/unix/proj/minimal".
