Please help me first: Is this a rewrite of the existing driver or an
update/extension/2.6-compatibility patch? In the latter case, sending
your changes in form of a real patch would be preferred for reviews
("svn diff" may help if you work with RTnet svn).

Wolfgang, is this due to the original Linux driver not being a module?

Transmission is not working, maybe its IRQ line setup is broken. Thus
you get a full queue after a while - a short while if RTmac/TDMA is running.
What is your precise setup? I assume it's latest RTnet, but which I-pipe
patch, which Xenomai version? Just to have a common ground for the
discussion.

I would prefer to leave first detail comments up to Wolfgang... :->
Thanks for sharing your work! I'm sure we will be able to resolve
remaining issues and then merge an updated driver into RTnet.
