Thanks for the clarification. (I see - it is IS_LWP on i386.)

> In other words - that is not a condition of recursive lock attempt

So the order of splsoftnet() and mutex_enter(softnet_lock)
cannot explain a possible recursive locking attempt, right?
I'm afraid we will not find out where the panic Wolfgang
reported could have come from without more information.
Since the current code works at least for Wolfgang and me
I'll close the PR now.
