After moving mlnx interfaces to switchdev mode in sriov, it will reset that interface and may change its name and also will need ifup in order to get back the previous configuration. So adding a udev rule and ifup command the save the interface name and its configuration Change-Id: Ib4f384da344344f9e2ec666b0d8dbae441f24568 Closes-Bug: 1816710
