tristate "Software RDMA over TCP/IP (iWARP) driver"

depends on INET && INFINIBAND && 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.
