	help
	  This option allows the NFS client and server to support
	  an RDMA-enabled transport.

	  To compile RPC client RDMA transport support as a module,
	  choose M here: the module will be called xprtrdma.

	  If unsure, say N.

config SUNRPC_REGISTER_V4
	bool "Register local RPC services via rpcbind v4 (EXPERIMENTAL)"
	depends on SUNRPC && EXPERIMENTAL
	default n
	help
	  Sun added support for registering RPC services at an IPv6
	  address by creating two new versions of the rpcbind protocol
	  (RFC 1833).

	  This option enables support in the kernel RPC server for
	  registering kernel RPC services via version 4 of the rpcbind
	  protocol.  If you enable this option, you must run a portmapper
	  daemon that supports rpcbind protocol version 4.

	  Serving NFS over IPv6 from knfsd (the kernel's NFS server)
	  requires that you enable this option and use a portmapper that
	  supports rpcbind version 4.

	  If unsure, say N to get traditional behavior (register kernel
	  RPC services using only rpcbind version 2).  Distributions
	  using the legacy Linux portmapper daemon must say N here.

config RPCSEC_GSS_KRB5

	depends on SUNRPC && EXPERIMENTAL
	select SUNRPC_GSS

	select CRYPTO_DES
	select CRYPTO_CBC
	help
	  Choose Y here to enable Secure RPC using the Kerberos version 5
	  GSS-API mechanism (RFC 1964).

	  Secure RPC calls with Kerberos require an auxiliary user-space
	  daemon which may be found in the Linux nfs-utils package
	  available from http://linux-nfs.org/.  In addition, user-space
	  Kerberos support should be installed.

	  If unsure, say N.

config RPCSEC_GSS_SPKM3
	tristate "Secure RPC: SPKM3 mechanism (EXPERIMENTAL)"
	depends on SUNRPC && EXPERIMENTAL
	select SUNRPC_GSS
	select CRYPTO
	select CRYPTO_MD5
	select CRYPTO_DES
	select CRYPTO_CAST5
	select CRYPTO_CBC
	help
	  Choose Y here to enable Secure RPC using the SPKM3 public key
	  GSS-API mechansim (RFC 2025).

	  Secure RPC calls with SPKM3 require an auxiliary userspace
	  daemon which may be found in the Linux nfs-utils package
	  available from http://linux-nfs.org/.

	  If unsure, say N.
