Subject: [PATCH rdma-next] RDMA/mlx5: Relax DCS QP creation checks
Date: Mon, 30 Aug 2021 13:48:49 +0300	[thread overview]
Message-ID: <> (raw)

From: Lior Nahmanson <>

In order to create DCS QPs, we don't need to rely on both
log_max_dci_stream_channels and log_max_dci_errored_streams capabilities.

Fixes: 11656f593a86 ("RDMA/mlx5: Add DCS offload support")
Signed-off-by: Lior Nahmanson <>
Signed-off-by: Leon Romanovsky <>

Please add this patch in the upcoming PR for the feature that was
accepted in this cycle.
