The array currently supports only port ID as destination actions. This patchset adds the below supports for MLX5 PMD driver: - Supports the metadata register Cx preserve capability query. - Supports the jump action support as one of destination of array. - Supports the modify action only impact on the one of destination. The examples for the E-Switch flow use case and result as below: set sample_actions 0 port_id id 1 / end flow create 0 ingress transfer pattern eth / end actions sample ratio 1 index 0 / jump group 1 / end flow create 1 ingress transfer group 1 pattern eth / end actions set_mac_dst mac_addr 00:aa:bb:cc:dd:ee / port_id id 2 / end The flow results all the matched ingress packets are mirrored to port id 1 and go to group 1. In the group 1, packets are modified with the destination mac and sent to port id 2. v2: * Rebase * Update commit message and document description Jiawei Wang (5): common/mlx5: query register c preserve capability via DevX net/mlx5: support E-Switch mirroring and jump in one flow net/mlx5: extend the skip scale flag net/mlx5: update modify actions support for E-Switch mirror doc: update the advanced E-switch mirroring supports doc/guides/nics/mlx5.rst | 2 + doc/guides/rel_notes/release_21_02.rst | 7 ++ drivers/common/mlx5/mlx5_devx_cmds.c | 2 + drivers/common/mlx5/mlx5_devx_cmds.h | 1 + drivers/common/mlx5/mlx5_prm.h | 4 +- drivers/net/mlx5/mlx5_flow.c | 203 +++++++++++++++++++++++---------- drivers/net/mlx5/mlx5_flow.h | 23 +++- drivers/net/mlx5/mlx5_flow_dv.c | 92 +++++++++------ 8 files changed, 235 insertions(+), 99 deletions(-)
