The plugin binary actually functions in two modes. The first mode is a regular CNI plugin. The second mode (when stared with "daemon" arg) runs a DHCP client daemon. When executed as a CNI plugin, it issues an RPC request to the daemon for actual processing. The daemon is required since a DHCP lease needs to be maintained by periodically renewing it. One instance of the daemon can server arbitrary number of containers/leases.
