Subject: [PATCH rdma-next] IB/mlx5: Return failure when rts2rts_qp_counters_set_id is not supported
Date: Sun, 26 Jan 2020 19:17:08 +0200 [thread overview]
Message-ID: <20200126171708.5167-1-leon@kernel.org> (raw)
From: Mark Zhang <markz@mellanox.com>
When bind a QP with a counter and the QP state is not RESET, return
failure if the rts2rts_qp_counters_set_id is not supported. This is
to prevent cases like manual bind for Connect-IB devices from returning
success when the feature is not supported.
Fixes: d14133dd4161 ("IB/mlx5: Support set qp counter")
