FWIW, the LOR still is there.  I was seeing it yesterday while
fiddling with the ipfw and natd rc.d scripts.

lock order reversal:
 1st 0xc1a36090 inp (divinp) @ /usr/src/sys/modules/ipdivert/../../netinet/ip_divert.c:350
 2nd 0xc0a51918 PFil hook read/write mutex (PFil hook read/write mutex) @ /usr/src/sys/net/pfil.c:73
