Currently, VNX driver provides SP toggle feature which would try another IP if primary IP became unavailable. Unfortunately, driver did not protect the toggling SP logic in a lock section so if many toggles happen in a short time, race condition may occur and driver would try the unavailable IP again. This fix provides a safe way to toggle and swap current primary IP to avoid above mentioned issue. Change-Id: I4af960a625dafbe868f12d275cf9b34eb254a388 Closes-Bug: 1526600
