[ upstream commit 15c80155874e
("net/mlx5: block RSS action without Rx queue") ]
This patch modifies function mlx5_flow_validate_action_rss(), to
prevent the setting of rule with rss action, but without specifying
any queues.
For example:
flow create 0 ingress pattern end actions rss queues end / end
