arp_ignore for lo-device

I just found out how to set arp_ignore for separate interfaces, but not for the loopback-device. How can I preven...

ipconfig problem if multiple devices are up
Hi, it seems that ipconfig has a problem if multiple devices are up and connected to the same network. It seems that it uses the wrong socket/device index to compare it to incoming packet. To be more precise, the packet gets discarded in do_pkt_recv as the ifindex from state differs always from the incoming packet To reproduce create two tap devices: $ sudo tunctl -u uli -t tap0
