lwip examples

[Stefan Kalkowski]

Hello Amadeo,

thank you for pointing us out to the build-problem in the linux_drivers
repository. We immediately fixed that problem. You can checkout the fix
from our subversion repository.

With respect to your problems related to lwip. I assume that you
compiled lwip and libc as static libraries, as ldso and shared libraries
aren't supported for Genode/Fiasco.OC yet?

Without knowing much details I would guess it's a configuration issue.
Could you please provide some information with respect to your
test-environment, like what hardware or VM you use, especially which NIC
you've enabled? Moreover, the init-configuration and the complete serial
output would be helpful.

But even when we fix your (probably configuration-)issues it's unlikely
that the NIC service will work out of the box now, because it's based on
the signalling framework, which isn't supported yet. But we work on
that, and it will be supported at the latest by the upcoming release.
Nevertheless, the mentioned problems have nothing to do with a
non-functional signalling framework.

Regards
Stefan
