Automatic merge from submit-queue (batch tested with PRs 55247, 55324, 55261, 55147, 54052). If you want to cherry-pick this change to another branch, please follow the instructions <a href="https://github.com/kubernetes/community/blob/master/contributors/devel/cherry-picks.md">here</a>. Implement dummy device operation by netlink for ipvs proxier **What this PR does / why we need it**: Currently, we implement network interface operations, e.g. create a dummy device and delete a dummy interface via ip cmd and then collect the exist code. For example, we assume the following command: ``` ip link add kube-ipvs0 type dummy ``` returns 2 means the dummy device `kube-ipvs0` exists, see https://github.com/kubernetes/kubernetes/blob/master/pkg/proxy/ipvs/proxier.go#L1529 . However, from the man page of ip command, exit status 2 just means an error was reported by the kernel, see http://man7.org/linux/man-pages/man8/ip.8.html#EXIT_STATUS. So, that's a bug. This PR implements dummy device operation by netlink for ipvs proxier so that can get ride of ip command operations. **Which issue this PR fixes**: fixes #54054 **Special notes for your reviewer**: **Release note**: ```release-note NONE ``` /sig network /area kube-proxy /kind bug
