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

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