From 554604061979d656bbbec50f101526349cd5aa5f Mon Sep 17 00:00:00 2001 From: Shay Drory Date: Mon, 16 Aug 2021 08:41:08 +0300 Subject: net/mlx5: Let user configure max_macs param Currently, max_macs is taking 70Kbytes of memory per function. This size is not needed in all use cases, and is critical with large scale. Hence, allow user to configure the number of max_macs. For example, to reduce the number of max_macs to 1, execute:: $ devlink dev param set pci/0000:00:0b.0 name max_macs value 1 \ cmode driverinit $ devlink dev reload pci/0000:00:0b.0 Signed-off-by: Shay Drory Reviewed-by: Moshe Shemesh Reviewed-by: Parav Pandit Signed-off-by: Saeed Mahameed --- Documentation/networking/devlink/mlx5.rst | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'Documentation/networking/devlink') diff --git a/Documentation/networking/devlink/mlx5.rst b/Documentation/networking/devlink/mlx5.rst index 5b77863f9c88..d467e770906e 100644 --- a/Documentation/networking/devlink/mlx5.rst +++ b/Documentation/networking/devlink/mlx5.rst @@ -14,8 +14,12 @@ Parameters * - Name - Mode + - Validation * - ``enable_roce`` - driverinit + * - ``max_macs`` + - driverinit + - The range is between 1 and 2^31.
