Hi @SchSeba I am okay with the change, but not sure why it's an issue. for example, other cni's use alt-name as a way to restore the original VF name I think host-device cni uses this logic I know sriov-cni caches the cmdAdd anyways, so we can restore from cache, thus I am okay with this change.

@Eoghan1232 thanks for the comment!

the reason we need this change (it's better explained in the issue) is that we are not able to return the vf to the host network namespace with is original name because it contains the same name in alt-name.

btw if host-cni use this feature it also needs to remove the alt-name before it restore it or it will not work

thanks for the info. I'm happy for the merge :)
