The default one is OpenBSD.

Finishing the eCos port to include the IPv6 files. Most of those are
currently not even present...

Not that we're aware of, although (if a customer came along) Red Hat would
love to do it.

Removing the dependencies on the rest of the kernel. But note that this
stack wasn't ported very "cleanly". There are many issues, like namespace
issues and non-portable header files, that could cause people problems on
certain targets.

Use the io/eth layer, but don't be afraid of improving the API: there's
lots of improvements that could be made to reduce the number of copies, for
