Subject: [PATCH V1 rdma-next 06/24] RDMA/mlx5: Reject QP transport types not enabled by FW capability
Date: Tue, 10 Nov 2026 15:43:02 +0200 [thread overview]
Message-ID: <20261110134320.34408-7-yishaih@nvidia.com> (raw)
In-Reply-To: <20261110134320.34408-1-yishaih@nvidia.com>
check_qp_type() checks the FW capability only for XRC and DC. RC, UC
and UD QPs are created even if the FW does not report the matching
capability bit.
Check the rc, uc and ud capabilities as well, so that QP creation is
refused for a transport the FW does not support.
