>Description:
netstat -f ng on FreeBSD 7-STABLE returns an error.
# netstat -f ng
netstat: ng_socket.ko not found
netstat: ng_socket.ko not found
# kldstat

Preloaded ng_socket.ko does not correct an error.
I did not check with NETGRAPH_SOCKET compiled into kernel.
The problem does not show up on 6.4-STABLE
(FreeBSD *** 6.4-STABLE FreeBSD 6.4-STABLE #159: Fri Oct 2 23:42:26 UTC 2009)
There is another bug (probably related) with netgraph subsystem
mpd 5.[23] with config like
pppoe_client:
create bundle static B1
set iface route default
set ipcp ranges 0.0.0.0/0 0.0.0.0/0
create link static L1 pppoe
set link action bundle B1
set auth authname user
set auth password pass
set link max-redial 0
set link mtu 1460
set link keep-alive 10 60
set pppoe iface fxp0
set pppoe service ""
# set nat enable log
immediately exits on SIGSEGV on any (uncommented) "set nat enable ..." command.
