            Bug ID: 91471
           Summary: add and removing macvlan link caused this dump trace
           Product: Networking
           Version: 2.5
    Kernel Version: 3.13.0-32-generic
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1

          Assignee: shemminger@...ux-foundation.org
          Reporter: ray.qiu@...il.com
        Regression: No

It can be consistently reproduced.

 - Bring up a docker container
 - Create an ip link with type macvlan 
 - Move it to another netns for a container
 - Bring it up and assign ip address
 - Then, remove the link from the container and terminate the container.

 - Repeat the process again will cause this crash dump.
