expect ip a to show link in up state

[egernst]

When executing sudo docker run --runtime=kata-runtime alpine sh -c " ip a", I would expect to see the link state to be up. This is not the case. If you add a sleep 1 before executing ip a, ex: sudo docker run --runtime=kata-runtime alpine sh -c " sleep 1; ip a", the link is up as expected. Similarly, if I start an interactive terminal for a clear container, the link is in up state as expected.

Original issue, which can still be reproduced:
clearcontainers/runtime#885

@mcastelino @sboeuf @amshinde - FYI - this is still an issue...

I can't fully understand this issue and reproduce it.

Taking another look at this.

@egernst This does not really break anything, so closing this.
