>Description:
I am attempting to play around with ATM virtual interfaces but I am unable to get the interface to bind to an ip address without causing a kernel panic. I have tried to find documentation on this error but have failed. I am beginning to think it is a bug.

Here is an excerpt of what happens after configuring the atm intefrace("See How to repeat the problem for more specifics")
<<<
routeb# ifconfig atm0 10.1.1.1 netmask 255.255.255.0 up
panic: ipatm_nifstat: setaddr missing ip_nif
>How-To-Repeat:
Just run the following and make sure you have all the necessary netgraph + atm modules. Try the above kernel config.

ngctl -f - <<EOF
  mkpeer atmpif dummy link
  name .:dummy vatmpif1
EOF
ngctl -d mkpeer vatmpif1: ksocket link inet/dgram/udp
ngctl msg vatmpif1: setconfig \{ debug=1 pcr=353207 macaddr=00:09:c0:00:00:ce \}
atm set netif hva1 atm 5
atm attach hva1 sigpvc

#Bind to an ip on atm0 - 5 and you get a panic
ifconfig atm0 10.1.1.1 netmask 255.255.255.0 up
