2 tristate "Software RDMA over TCP/IP (iWARP) driver"
3 depends on INET && INFINIBAND && LIBCRC32C
4 depends on INFINIBAND_VIRT_DMA
7 This driver implements the iWARP RDMA transport over
8 the Linux TCP/IP network stack. It enables a system with a
9 standard Ethernet adapter to interoperate with a iWARP
10 adapter or with another system running the SIW driver.
11 (See also RXE which is a similar software driver for RoCE.)
13 The driver interfaces with the Linux RDMA stack and
14 implements both a kernel and user space RDMA verbs API.
15 The user space verbs API requires a support
16 library named libsiw which is loaded by the generic user
17 space verbs API, libibverbs. To implement RDMA over
18 TCP/IP, the driver further interfaces with the Linux
19 in-kernel TCP socket layer.
