+config RDMA_SIW
+ tristate "Software RDMA over TCP/IP (iWARP) driver"
+ depends on INET && INFINIBAND && LIBCRC32C && 64BIT
+ select DMA_VIRT_OPS
+ 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.
