> Subject: [dpdk-dev] [PATCH v9 0/3] support the flow-based traffic sampling
> 
> This patch set implement the flow-based traffic sampling.
> 
> The solution is introduced a new rte_flow action that will sample the
> incoming traffic and send a duplicated traffic with the specified ratio to the
> application, while the original packet will continue to the target destination.
> 
> If the sample ratio value be set to 1, means that the packets would be
> completely mirrored. The sample packet can be assigned with different set of
> actions from the original packet.

> 
> v9:
> * Rebase patches based on the latest code.
> * Separate the MLX5 PMD changes into another patches.
> 
> v8:
> * Rebase patches based on the latest code.
> * Update the offloads dependencies document for sample flow.
> * Update sample flow limitation document.
> 
> v7:
> * Removed change in [PATCH 12/12] net/mlx5: support the native port id
> actions for mirroring, should use sample action.
> * Update the PMD code to match the new rdma-core API for mirroring.
> * Optimize the sample flow split routine.
> * Update code changes and commit log based on the review.
> * Add E-Switch sample flow limitation document.

> v6:
> * Update the function that restore vport through metadata register c0 for

> * Add multiple destination support.
> * Support the remote mirroring with different encapsulation header.
