Add support for dedicated DPDK firmware variant which has equal stride super-buffer Rx mode. The Rx mode uses bucket mempool manager which supports allocation of contiguos block of mbufs.
It allows to achieve higher packet rate on Rx than traditional single packet Rx mode. Also the Rx mode supports rte_flow MARK and FLAG actions. It should be applied on top of [1], [2], [3], [4], [5].
