What I did suspect here is that some kernel code takes softnet_lock
without a splsoftnet() before, and a softnet handler gets to run
and happens to borrow the same thread context. In that case,
the diagnostic check could fire even if the softnet handler
doesn't do anything wrong.
Can this happen?

Matthias
