Yes, I've read it on the mailing list.

I think this is the way to go. There is already some hacking on PPP in 
my port, which could lead to some confusion, as it is not identical to 
the lwIP codebase. Also it does only work in a polled environment like 
mine, so it might not be much use of the broad community. I don't know 
how we should proceed with this?

Well, the tests I have been doing were successful. But I could only test 
on the synthetic target as my hardware lacks ethernet support. Some 
broader testing on real hardware would be great.

I'll merge the latest changes from the lwip 1.3.1 release and make a new 
release for review and testing.
