Subject: [RFC PATCH iproute2-next 3/3] rdma: Document the new "pid" criteria for auto mode
Date: Sun, 26 Jul 2020 14:20:11 +0300
Message-ID: <20200726112011.75905-4-leon@kernel.org> (raw)
In-Reply-To: <20200726112011.75905-1-leon@kernel.org>

From: Mark Zhang <markz@mellanox.com>

Document the new supported criteria of auto mode. Examples:
$ rdma statistic qp set link mlx5_2/1 auto pid on
$ rdma statistic qp set link mlx5_2/1 auto pid,type on
