If anyone has any objections, please let me know. ------------------ From: Yuyang Huang [ Upstream commit 3cbbc9fa33382d03f2813118e672eb318eba9cde ] During address teardown, the inetaddr notifier may be called multiple times for the same interface. Ignore NETDEV_DOWN events if the RIF has already been destroyed, rather than returning -EEXIST, which aborts the notifier chain.
