MLX5 E-Switch mirroring is implemented as multiple destination array in
one steering table. The array currently supports only port ID as
destination actions.

This RFC 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.

Jiawei Wang (4):
  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: supports modify one port in E-Switch mirroring
