Multi-Packet Rx Queue (MPRQ a.k.a Striding RQ) can further save PCIe bandwidth by posting a single large buffer for multiple packets. Instead of posting a buffer per a packet, one large buffer is posted in order to receive multiple packets on the buffer. A MPRQ buffer consists of multiple fixed-size strides and each stride receives one packet. Rx packet is mem-copied to a user-provided mbuf if the size of Rx packet is comparatively small, or PMD attaches the Rx packet to the mbuf by external buffer attachment - rte_pktmbuf_attach_extbuf(). A mempool for external buffers will be allocated and managed by PMD. Signed-off-by: Yongseok Koh <yskoh@mellanox.com> Acked-by: Shahaf Shuler <shahafs@mellanox.com>
