How is that possible? What communication is stopped? Can you
provide 'tcpdump -len arp' output for all devices involved? You have to
show us that some ARP reply is not sent when it should, or vice versa.

Use this doc:
http://www.linuxvirtualserver.org/docs/arp.html
1. The hidden interface approach
If some doc is buggy, send fix to the doc author.

I'm not sure what doc you are reading. If you look into the patch
you can see that there is an info how the feature is activated. There
is a description in proc.txt and ip-sysctl.txt. You have to send me an
URL to this buggy doc.
