> Subject: [dpdk-dev] [PATCH 00/28] net/mlx5: support LRO
>
> Introduction:
> LRO (Large Receive Offload) is intended to reduce host CPU overhead when
> processing Rx TCP packets.
> LRO works by aggregating multiple incoming packets from a single stream
> into a larger buffer, before they are passed higher up the networking stack.
> Thus reducing the number of packets that have to be processed.
>
> Use:
> MLX5 PMD will query the HCA capabilities on initialization to check if LRO is
> supported and can be used.
> LRO in MLX5 PMD is intended for use by applications using a relatively small
> number of flows.
> LRO support can be enabled only per port.
> In each LRO session, packets of the same flow will be coalesced until one of
> the following occur:
> * Buffer size limit is exceeded.
> * Session timeout is exceeded.
> * Packet from a different flow is received on the same queue.
>
> When LRO session ends the coalesced packet is passed to the PMD, which
> will update the header fields before passing the packet to the application.
> For efficient memory utilization, the MPRQ mechanism is used.
> Support of Non-LRO flows will not be impacted.
>
> Existing API:
> Offload capability DEV_RX_OFFLOAD_TCP_LRO will be used to indicate
> device supports LRO.
> testpmd command-line option "-enable-lro" will be used to request LRO
> feature enable on application start.
> testpmd rx_offload "tcp_lro" on or off will be used to request LRO feature
> enable or disable during application runtime.
> Offload flag PKT_RX_LRO will be used. This flag can be set in Rx mbuf to
> indicate this is a LRO coalesced packet.
>
> New API:
> PMD configuration parameter lro_timeout_usec will be added.
> This parameter can be used by application to select LRO session timeout (in
> microseconds).
> If this value is not specified, the minimal value supported by device will be
> used.
>
> Known limitations:
> mbuf head-room is zero for any packet if LRO is configured in the port.
> Keep CRC offload cannot be supported with LRO.
> CQE compression is not supported with LRO.
>
