Re: [lwip-users] LWIP, PPP and GPRS

tcpip_init is necessary for PPP. Just take a look at what it
does and you'll probably figure out why. Hint: PPP also uses the
tcpip_callback routine, which is implemented in the same file as
tcpip_init.

Do not call any of the fsm_, lcp_, or ipcp_ routines yourself. that will
all be done by PPP as necessary.
