[PATCH rdma-next] RDMA/mlx5: Relax DCS QP creation checks

From: Leon Romanovsky
Date: Mon Aug 30 2021 - 06:49:10 EST


From: Lior Nahmanson <liorna@xxxxxxxxxx>

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")
