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.) 14 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. 22
