Subject: [PATCH rdma-next v1 11/11] RDMA/mlx5: Add optional counter support in get_hw_stats callback
Date: Wed, 15 Sep 2021 02:07:30 +0300 [thread overview]
Message-ID: <584d4fb2a5e3fe4b6390f5ea43cf96f65625b026.1631660727.git.leonro@nvidia.com> (raw)
In-Reply-To: <cover.1631660727.git.leonro@nvidia.com>
From: Aharon Landau <aharonl@nvidia.com>
When get_hw_stats is called, query and return the optional counter
statistic as well.
