Apparently this was never tested: early in the boot phase I get the following panic:

panic: spin lock netgraph worklist mutex not in order list

and indeed the witness code appears to have no knowledge of the netgraph spinlocks.

From what I can gather, you add the locking hierarchy to be enforced to spin_order_list in kern.mutex.c
