This plugin doesn't have any dependency on DPDK or DPDK plugin but it can work with DPDK plugin enabled or disabled. It is observed that performace is better around 30% when DPDK plugin is disabled, as DPDK plugin registers own buffer manager, which needs to deal with additional metadata in each packet.
DPKD plugin can be disabled by adding following config to the startup.conf.
