On master branch:

ppp = pppo..._create(...);

ip4_addr_t addr;
IP4_ADDR(&addr, 192,168,0,1); 
ppp_set_ipcp_ouraddr(ppp, &addr);

ppp_connect(ppp, 0);

We are now able to add as many macros as necessary to change the PPP 
configuration without changing the API but I don't want to bloat ppp.h 
with macros for every possible config option, most are close to useless 
anyway, which options would you need ?
