RDMA/mlx5: Create UCAP char devices for supported device capabilities

Browse source

Create UCAP character devices when probing an IB device with supported
firmware capabilities.

If the RDMA_CTRL general object type is supported, check for specific
UCTX capabilities:
Create /dev/infiniband/mlx5_perm_ctrl_local for RDMA_UCAP_MLX5_CTRL_LOCAL
Create /dev/infiniband/mlx5_perm_ctrl_other_vhca for RDMA_UCAP_MLX5_CTRL_OTHER_VHCA
