Saeed Mahameed says:
====================
mlx5-updates-2021-04-13
mlx5 core and netdev driver updates
1) E-Switch updates from Parav,
1.1) Devlink parameter to control mlx5 metadata enablement for E-Switch
1.2) Trivial cleanups for E-Switch code
1.3) Dynamically allocate vport steering namespaces only when required
2) From Jianbo, Use variably sized data structures for Software steering
3) Several minor cleanups
====================
