Never a good deed that goes unpunished...

I just tried to run the port trafshow but when I do, it says:

  trafshow: BIOCSETIF: ix0: Device not configured

Tcpdump also says:

  tcpdump: ix0: Device not configured

Which surprises me because the network has been working since I installed 
2.0.5 (now running 2.1-stable).

Netstat -i says:

..and ifconfig -a says:

lp0: flags=8810<POINTOPOINT,SIMPLEX,MULTICAST> mtu 1500
ix0: flags=63<UP,BROADCAST,NOTRAILERS,RUNNING> mtu 1500
	inet 205.148.224.9 netmask 0xffffff00 broadcast 205.148.224.255
lo0: flags=8009<UP,LOOPBACK,MULTICAST> mtu 16384
	inet 127.0.0.1 netmask 0xff000000 
sl0: flags=c010<POINTOPOINT,LINK2,MULTICAST> mtu 552
tun0: flags=8010<POINTOPOINT,MULTICAST> mtu 1500

...and before I tried to use any of this, I changed the kernel to add the 
packet filter pseudo-device:

----
[ ... ]
pseudo-device	loop
pseudo-device	ether
pseudo-device	log
pseudo-device	sl	1
pseudo-device	tun	1
pseudo-device	pty	16
pseudo-device	gzip		# Exec gzipped a.out's
pseudo-device	speaker
pseudo-device	bpfilter	4
----

Is this the driver's gentle way of telling me it can't be placed into 
promiscuous mode? (I've also tried trafshow -p)
