Subject: [patch net-next v2 12/12] net/mlx5: Move eswitch port metadata devlink param to flow eswitch code
From: Jiri Pirko <jiri@...dia.com>
Move the param registration and handling code into the eswitch offloads
code as they are related to each other. No point in having the
devlink param registration done in separate file.
Signed-off-by: Jiri Pirko <jiri@...dia.com>

v1->v2:
- fixed uninitialized variable issue in esw_port_metadata_set()
