The sample packet can be assigned with different set of actions from the original packet.\n\nMLX5 PMD driver will be responsible for validate and translate the sample action while creating a flow.\n\nv4:\n* Rebase.\n* Fix the coding style issue.\n\nv3:\n* Remove 'const' of ratio field.\n* Update description and commit messages.\n\nv2:\n* Rebase patches based on the latest code.\n* Update rte_flow and release documents.\n* Fix the compile error.\n* Removed unnecessary change in [PATCH 7/8] net/mlx5: update the metadata register c0 support since FDB will use 5-tuple to do match.\n* Update changes based on the comments.\n\nJiawei Wang (7):\n ethdev: introduce sample action for rte flow\n common/mlx5: glue for sample action\n common/mlx5: query sampler object capability via DevX\n net/mlx5: add the validate sample action\n net/mlx5: split sample flow into two sub flows\n net/mlx5: update translate function for sample action\n app/testpmd: add testpmd command for sample action\n\n app/test-pmd/cmdline_flow.c | 285 +++++++++++++++-\n doc/guides/prog_guide/rte_flow.rst | 25 ++\n drivers/common/mlx5/Makefile | 5 +\n drivers/common/mlx5/linux/meson.build | 2 +\n drivers/common/mlx5/linux/mlx5_glue.c | 15 +\n drivers/common/mlx5/linux/mlx5_glue.h | 12 +\n drivers/common/mlx5/mlx5_devx_cmds.c | 27 ++\n drivers/common/mlx5/mlx5_devx_cmds.h | 1 +\n drivers/common/mlx5/mlx5_prm.h | 51 +++\n drivers/net/mlx5/linux/mlx5_os.c | 14 +\n drivers/net/mlx5/mlx5.c | 11 +\n drivers/net/mlx5/mlx5.h | 4 +\n drivers/net/mlx5/mlx5_flow.c | 274 ++++++++++++++-\n drivers/net/mlx5/mlx5_flow.h | 51 ++-\n drivers/net/mlx5/mlx5_flow_dv.c | 627 +++++++++++++++++++++++++++++++++-\n lib/librte_ethdev/rte_flow.c | 1 +\n lib/librte_ethdev/rte_flow.h | 30 ++\n 17 files changed, 1400 insertions(+), 35 deletions(-)" }
