1config RDMA_SIW2 tristate "Software RDMA over TCP/IP (iWARP) driver"3 depends on INET && INFINIBAND4 depends on INFINIBAND_VIRT_DMA5 select LIBCRC32C6 select CRYPTO7 select CRYPTO_CRC32C8 help9 This driver implements the iWARP RDMA transport over10 the Linux TCP/IP network stack. It enables a system with a11 standard Ethernet adapter to interoperate with a iWARP12 adapter or with another system running the SIW driver.13 (See also RXE which is a similar software driver for RoCE.)14 15 The driver interfaces with the Linux RDMA stack and16 implements both a kernel and user space RDMA verbs API.17 The user space verbs API requires a support18 library named libsiw which is loaded by the generic user19 space verbs API, libibverbs. To implement RDMA over20 TCP/IP, the driver further interfaces with the Linux21 in-kernel TCP socket layer.22
