+config RDMA_SIW
+	tristate "Software RDMA over TCP/IP (iWARP) driver"
+	depends on INET && INFINIBAND
+	depends on 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.
