We have never had an AR card to test the netgraph code with.
The netgraph code was done "in theory", but is waiting at the
("well that's all the hard work done" stage, for someone with a card
to show up..)
Basically it is the same code as in the Sr driver and a prorpretary
card at Whistle.
I will be out of touch for a day or two but if you would like to help me
get it going
send me some email and we can see what we can do..
The fact that you have it running in the old format shows that all the
information
needed is there.. I just need to figure out what I've missed out..

With netgraph, the ar device should not HAVE a ifconfig entry..
if it doesm that that is coding problem straight away..
