Subject: [dpdk-dev] [PATCH 0/3] net/mlx5: add Multi-Packet Rx support
Date: Wed, 2 May 2018 16:20:51 -0700 [thread overview]
Message-ID: <20180502232054.7852-1-yskoh@mellanox.com> (raw)
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.
This patchset should be applied after:
net/mlx5: add new Memory Region support
Yongseok Koh (3):
net/mlx5: separate filling Rx flags
net/mlx5: add a function to rdma-core glue
net/mlx5: add Multi-Packet Rx support
