1config RDMA_SIW 2 tristate "Software RDMA over TCP/IP (iWARP) driver" 3 depends on INET && INFINIBAND && CRYPTO_CRC32 4 help 5 This driver implements the iWARP RDMA transport over 6 the Linux TCP/IP network stack. It enables a system with a 7 standard Ethernet adapter to interoperate with a iWARP 8 adapter or with another system running the SIW driver. 9 (See also RXE which is a similar software driver for RoCE.) 10 11 The driver interfaces with the Linux RDMA stack and 12 implements both a kernel and user space RDMA verbs API. 13 The user space verbs API requires a support 14 library named libsiw which is loaded by the generic user 15 space verbs API, libibverbs. To implement RDMA over 16 TCP/IP, the driver further interfaces with the Linux 17 in-kernel TCP socket layer. 18
