Subject: [PATCH v1] net/mlx5: fix meter creation default state
Date: Mon, 7 Mar 2022 10:00:35 +0200	[thread overview]
Message-ID: <20220307080035.1140326-1-rongweil@nvidia.com> (raw)

Disable means there is no packet drop in the meter. Meter is
active always but programmed with another CIR/CBS value.

If the user wants to disable the meter in creation, PMD calls
the disable() API manually after meter initialized.

Fixes: 444320186393 ("net/mlx5: support meter creation with policy")
