 8	This driver implements the iWARP RDMA transport over
 9	the Linux TCP/IP network stack. It enables a system with a
10	standard Ethernet adapter to interoperate with a iWARP
11	adapter or with another system running the SIW driver.
12	(See also RXE which is a similar software driver for RoCE.)

14	The driver interfaces with the Linux RDMA stack and
15	implements both a kernel and user space RDMA verbs API.
16	The user space verbs API requires a support
17	library named libsiw which is loaded by the generic user
18	space verbs API, libibverbs. To implement RDMA over
19	TCP/IP, the driver further interfaces with the Linux
20	in-kernel TCP socket layer.
