orabug: 14470382 When Dom0''s network environment change, for example the issue, DomU should send send gratuitous ARP initially to notify how to reach it. To fix the bug, we should modify backend and frontend at the same time. For fixing frontend, i filer the new bug 16182568. The review only to backend. For fixing the backend, I have 4 patch for review. Thanks, Jason
