951 | Some devices are not allowed to change network namespace: loopback, bridge, | |
952 | ppp, wireless. These are network namespace local devices. In such case | |
953 | .B ip | |
954 | tool will return "Invalid argument" error. It is possible to find out if device is local | |
955 | to a single network namespace by checking | |
