Because the patch fix intern bug of oracle bug queue, I have test some 
netfontends( v2.6.32, v2.6.39 and
the latest kernel of Ubuntu 1104 ) on variable netbackend ( v2.6.18, 
v2.6.32 and v2.6.39) for more time, no
other issue be found.

But i don't test classic-xen trees, i will test for whole day at tomorrow.

Yes, you are right. But if no other issue be introduced, sending 
gratuitous ARP initiative will be better.
So, Our trouble is which issue will be introduced by the patch at now? I 
don't found until now. If you have
already thought of some bug, would you like to tell me. I will try to 
fix it.
