Issue Description

Type: feature request

Describe what feature you want

When creating the kata pod, the kata runtime failed to add ip v4 route to kata agent.
"Failed to add IP v4 route (src: , dst: , gtw: 169.254.1.1,Err: Network unreachable (os error 101))"

Can you remove the onlink flag of routes in pod netns? So we can create kata containers.

Additional context

[mars1024]

Could you help to append more detailed info here? E.g., hybridnet version, kata version and OS kernel.

And IMO, kata runtime is using CNI in a different way compared with container runtime, so maybe some code changes will be done after a later discussion among maintainers.
