IB/mlx5: Remove support for IB_DEVICE_LOCAL_DMA_LKEY
Commit 96249d70dd70 ("IB/core: Guarantee that a local_dma_lkey is available") allows ULPs that make use of the local dma key to keep working as before by allocating a DMA MR with local permissions and converted these consumers to use the MR associated with the PD rather then device->local_dma_lkey. ConnectIB has some known issues with memory registration using the local_dma_lkey (SEND, RDMA, RECV seems to work ok). Thus don't expose support for it (remove device->local_dma_lkey setting), and take advantage of the above commit such that no regression is introduced to working systems. The local_dma_lkey support will be restored in CX4 depending on FW capability query. Signed-off-by: Sagi Grimberg <sagig@mellanox.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
