* Add --collector.netdev.device-whitelist flag Sometimes it is desired to monitor only one netdev. The golang regexp does not support a negated regex, so the ignored-devices flag is too cumbersome for this task. This change introduces a new flag: accept-devices, which is mutually exclusive to ignored-devices. This flag allows specifying ONLY the netdev you'd like.
