Correction. It appeared to work, but it doesn't. Setting arp_filter to 1
does only send 1 ARP reply, but always with the MAC address of eth0.
So I guess I will have to apply the patch. BUT on my system it doesn't
apply cleanly to kernel 2.4.20.
Could someone please confirm that it doesn't? I almost bothered a kernel
driver maintainer with something simple, don't want to bother anyone
