It enables a system with a 9 standard Ethernet adapter to interoperate with a iWARP 10 adapter or with another system running the SIW driver. 11 (See also RXE which is a similar software driver for RoCE.) 12 13 The driver interfaces with the Linux RDMA stack and 14 implements both a kernel and user space RDMA verbs API. 15 The user space verbs API requires a support 16 library named libsiw which is loaded by the generic user 17 space verbs API, libibverbs. To implement RDMA over 18 TCP/IP, the driver further interfaces with the Linux 19 in-kernel TCP socket layer. 20
