 Hi, just wanted to remind that the PR should be reopened as
 the problem is not fixed. I meanwhile added many extra KASSERTs to try
 to track down the bug. It looks like an npf_connkey_t ends up inserted
 into two different hash buckets (with disastrous results). Have
 yet to find the root cause but the code path where I've seen this
 happen is:
 
 npf_conndb_insert()
 npf_conn_setnat()
 npf_do_nat()
 npf_packet_handler()
 pfil_run_hooks()
 ipintr()
 softintr_dispatch()
