Re: lwIP port status

lwIP 1.3.1 was finally released today.

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


In view of the known issues with the older eCos lwIP 1.1.1 port and the
many fixes to the master lwIP sources over the intervening years, I'm
keen to get this committed to eCos CVS as soon as possible.

Having reviewed the lwIP ChangeLog, I think it makes sense to simply
replace the older lwIP port in the eCos CVS trunk (tagging the
repository before the commit). There are known issues with lwIP PPP
which need to be addressed upstream. In the meantime, eCos users wishing
to work with lwIP PPP should be better off hacking on the lwIP 1.3.1
stack where necessary rather than using the older port.

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?


What is the status of your testing of your lwIP 1.3.x port now? Are you
comfortable that it is stable under heavy CPU and network loads?

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.
