	tristate "Software RDMA over TCP/IP (iWARP) driver"

	depends on INET && INFINIBAND && CRYPTO_CRC32

	help

	This driver implements the iWARP RDMA transport over

	the Linux TCP/IP network stack. It enables a system with a

	standard Ethernet adapter to interoperate with a iWARP

	adapter or with another system running the SIW driver.

	(See also RXE which is a similar software driver for RoCE.)



	The driver interfaces with the Linux RDMA stack and

	implements both a kernel and user space RDMA verbs API.

	The user space verbs API requires a support

	library named libsiw which is loaded by the generic user

	space verbs API, libibverbs. To implement RDMA over

	TCP/IP, the driver further interfaces with the Linux

	in-kernel TCP socket layer.
