Subject: [PATCH rdma-next 2/2] IB/mlx5: Expose RoCE accelerator counters
Date: Wed, 15 Jan 2020 16:54:59 +0200 [thread overview]
Message-ID: <20200115145459.83280-3-leon@kernel.org> (raw)
In-Reply-To: <20200115145459.83280-1-leon@kernel.org>
From: Avihai Horon <avihaih@mellanox.com>
Introduce the following RoCE accelerator counters:
* roce_adp_retrans - number of adaptive retransmission for RoCE traffic.
* roce_adp_retrans_to - number of times RoCE traffic reached time out
due to adaptive retransmission.
* roce_slow_restart - number of times RoCE slow restart was used.
* roce_slow_restart_cnps - number of times RoCE slow restart
generate CNP packets.
* roce_slow_restart_trans - number of times RoCE slow restart change
state to slow restart.
