Thanks.
Sorry, I didn't think this one through. I'll keep looking for the
real problem.
Is it possible that you merged my earlier patch to handle all fragment
sizes?
Cause earlier versions had exactly that problem.
I don't think so. We merge from amd-staging-4.12. Was your earlier patch
already submitted to the branch?
No, I haven't committed it yet. Just though that Roger might have merged
that in the hybrid branch and you picked it up there.
Christian.
Regards,
Felix
