	help
	  Userspace InfiniBand Management Datagram (MAD) support.  This
	  is the kernel side of the userspace MAD support, which allows
	  userspace processes to send and receive MADs. You will also
	  need libibumad from rdma-core
	  <https://github.com/linux-rdma/rdma-core>.

config INFINIBAND_USER_ACCESS
	tristate "InfiniBand userspace access (verbs and CM)"
	depends on MMU
	help
	  Userspace InfiniBand access support.  This enables the
	  kernel side of userspace verbs and the userspace
	  communication manager (CM).  This allows userspace processes
	  to set up connections and directly access InfiniBand
	  hardware for fast-path operations.  You will also need
	  libibverbs, libibcm and a hardware driver library from
	  rdma-core <https://github.com/linux-rdma/rdma-core>.

	help
	  On demand paging support for the InfiniBand subsystem.
	  Together with driver support this allows registration of
	  memory regions without pinning their pages, fetching the
	  pages on demand instead.

config INFINIBAND_ADDR_TRANS
	bool "RDMA/CM"
	depends on INFINIBAND
	default y
	help
	  Support for RDMA communication manager (CM).
	  This allows for a generic connection abstraction over RDMA.

config INFINIBAND_ADDR_TRANS_CONFIGFS
	bool
	depends on INFINIBAND_ADDR_TRANS && CONFIGFS_FS && !(INFINIBAND=y && CONFIGFS_FS=m)
	default y
	help
	  ConfigFS support for RDMA communication manager (CM).
	  This allows the user to config the default GID type that the CM
	  uses for each device, when initiaing new connections.
