Netgraph: Ethernet interfaces missing from persistent node list

[benjamin at cactus.org]

Using ngctl as suggested in the "All About Netgraph" Daemon News
article (http://people.freebsd.org/~julian/netgraph.html ) by Archie
Cobbs I get the following output:

root at ntp-2# nghook -a fxp0: divert
nghook: can't connect to node

root at ntp-2# ngctl list
There are 1 total nodes:
  Name: ngctl4352       Type: socket          ID: 00000005   Num hooks: 0

According to the article my four Ethernet interefaces (see ifconfig output below) should display
as persistent nodes.  Any reason why they do not appear?  I compiled a custom kernel on two separate
occasions, first to support IPFW/Dummynet, then later, Netgraph.

Thanks,
Tom Benjamin

##### kernel options added for 1st compile (IPFW)
options BRIDGE
options IPFIREWALL
options IPFIREWALL_VERBOSE
options IPFIREWALL_VERBOSE_LIMIT
options DUMMYNET
options NMBCLUSTERS
options HZ=1000
##### kernel options added for 2nd compile (NETGRAPH, plus forgot IPDIVERT in 1st compile)
options IPDIVERT
options NETGRAPH
##### end kernel options
