It enables a system with a 10 standard Ethernet adapter to interoperate with a iWARP 11 adapter or with another system running the SIW driver. 12 (See also RXE which is a similar software driver for RoCE.) 13 14 The driver interfaces with the Linux RDMA stack and 15 implements both a kernel and user space RDMA verbs API. 16 The user space verbs API requires a support 17 library named libsiw which is loaded by the generic user 18 space verbs API, libibverbs. To implement RDMA over 19 TCP/IP, the driver further interfaces with the Linux 20 in-kernel TCP socket layer. 21
