While trying to debug a USB network kext I find that I can't unload as the dlil isn't being destroyed.

Following the steps of the documentation.

Steps to reproduce (using a pegasus USB enet, but the same steps are reproducable with the Air's ENET dongle)

1> Load the IOKit kext
2> ifconfig en2 inet 192.168.1.2 netmask 255.255.255.0 up
3> arp it on both machines
4> Do some test, then...
5> ipconfig set en2 NONE
6> kextunload ...  Fails still has references
7> ifconfig -a (Still shows an active en2 interface?)

This looks like a bug in Snow Leopard?

Nothing I do will unload the kext even thought this is the documented techniques described in http://developer.apple.com/mac/library/documentation/DeviceDrivers/Conceptual/NetworkDriver/3_Tipsfolder/TipsonBringup.html
