[lwip-devel] PPP failure

[su_list]

Hi:

PPP in LWIP is failing when I am trying to setup a link with a given ISP.
The point to note is, with some of the phones I can connect successfully but
with some phones its failing regularly. I am using no-authentication in PPP.
I am attaching the LWIP prints for the failure case below. Can someone help
me debugging of why its failing in one phone and passing in the other. If
its needed plz let me know so that I can put the success case as well (dont
want to stretch the mail much longer).

LWIP prints for Failure case:
