Please check: http://www.kroah.com/log/linux/linux-staging-update.html It's for "drivers" and "filesystems". You don't need to modify the kernel infrastructure to add drivers and filesystems - but you need to change infrastructure to add new networking functionalities. Therefore i don't think, that this would work with the staging approach. Btw. how can we gain more interest and users to the evaluation of Kurts j1939 stack? I remember about 3 persons asking about it (even about details) - what happened to them? Regards, Oliver
