[lwip-users] PPP problems: IPCP obsolete option

I managed (with Paulo Silva) to make the Linux port work with PPP (not tap0). I got exactly to the point Fodor Peter got here: http://www.mail-archive.com/address@hidden/msg03856.html

I traced it to what appears to be that PPP has a part obsolete (?) The last transmission that is not answered is the first IPCP message: FF 03 80 21 01 01 00 16 03 06 00 00 00 00 81 06 00 00 00 00 83 06 00 00 00 00 6E DB 7E

FF 03: PPP encapsulation
80 21: PPP protocol - IPCP
01:    IPCP code 01: Configure-Request
01:    IP-Addresses (deprecated)

According to RFC 1332:
The use of the Configuration Option IP-Addresses has been deprecated. [...] This option SHOULD NOT be sent in a Configure-Request [...] Support for this option MAY be removed ... and it is not even described in the RFC !!!

Did anyone come across this? Has someone implemented the newer IPCP Configure Request option=03 that replaces this?

Thanks for any help...
