Subject: [net-next RFC v2 2/4] mlx5: Add queue number parameter to mlx5e_safe_switch_params()
Currently mlx5e_safe_switch_params() does not take a queue number and
assumes a global operation. This allows the function to handle individual
channels. Note that Global operations reset the individual channel
settings.
