It enables a system with a 9c0cf5bddSBernard Metzler standard Ethernet adapter to interoperate with a iWARP 10c0cf5bddSBernard Metzler adapter or with another system running the SIW driver. 11c0cf5bddSBernard Metzler (See also RXE which is a similar software driver for RoCE.) 12c0cf5bddSBernard Metzler 13c0cf5bddSBernard Metzler The driver interfaces with the Linux RDMA stack and 14c0cf5bddSBernard Metzler implements both a kernel and user space RDMA verbs API. 15c0cf5bddSBernard Metzler The user space verbs API requires a support 16c0cf5bddSBernard Metzler library named libsiw which is loaded by the generic user 17c0cf5bddSBernard Metzler space verbs API, libibverbs. To implement RDMA over 18c0cf5bddSBernard Metzler TCP/IP, the driver further interfaces with the Linux 19c0cf5bddSBernard Metzler in-kernel TCP socket layer. 20
