Following the the bug https://bugzilla.redhat.com/show_bug.cgi?id=2186372, we need to update the docs about how to mitigate packet drop during live migration.

We have introduced new flag to the bridge CNI to disable the container interface https://github.com/containernetworking/plugins/pull/997 and changed Kubevirt to ensue the interface is enabled after the migration is completed https://github.com/containernetworking/plugins/pull/997.

When the NetworkAttachmentDefinition is created using the bridge CNI, the disableContainerInterface should be spesifed.
See the following PR description for more details https://github.com/kubevirt/kubevirt/pull/11069
