I do not think that you need to be ifconfig'ed to talk to the packet capture mechanisms on Linux. Just go read netif_rx() and netif_receive_skb() in net/core/dev.c. So long as you can call with an skb, you are probably set. I'm not sure exactly what it means to be ifconfig-unfriendly - but as long as you can pretend to be a network device in some fashion, and produce SKB's, I think you should use the stock interfaces. ] ON HUMILITY: to err is human.
