Subject: [PATCH 06/11] RDMA: Check attr_mask during modify_qp
Date: Sat, 3 Oct 2020 20:20:06 -0300 [thread overview]
Message-ID: <6-v1-caa70ba3d1ab+1436e-ucmd_mask_jgg@nvidia.com> (raw)
In-Reply-To: <0-v1-caa70ba3d1ab+1436e-ucmd_mask_jgg@nvidia.com>
Each driver should check that it can support the provided attr_mask during
modify_qp. IB_USER_VERBS_EX_CMD_MODIFY_QP was being used to block
modify_qp_ex because the driver didn't check RATE_LIMIT.
