Hi Everyone,

We have had third-party validation on hardware tests (Thanks to Heinz
Junkes!) that ironed out a few minor issues. The network stack update
will be pushed tomorrow. *Fingers crossed* everything just works as
usual for rtems6 for anyone who isn't using libnetworking.

If you're planning to test it, please add your comments here so that we know someone is going to do it and wait for your feedback. The changes will not be pushed right away and we'll follow-up for your feedback.

There is a strong possibility that we will add lwip next, but no timeline has been decided for it yet. We plan to provide a performance analysis of lwip and libbsd networking (and maybe legacy networking as well)
