Hi,
This patch should corrects proxy arp feature in shaper devices forcing kernel 
checking (before sending ARP REPLY) for "physical" device (i.e. eth0) instead 
of "shaper" device (i.e. shaper0): in this way we avoid useless ARP REPLY and 
"IP CONFLICT" messages on client hosts.
More details in "readme.txt" file attached.

I already tested it for many days and it has been worked well.
Thank you for your great support.
Best Regards
Roberto arcomano
