It enables a system with a 7*c0cf5bddSBernard Metzler standard Ethernet adapter to interoperate with a iWARP 8*c0cf5bddSBernard Metzler adapter or with another system running the SIW driver. 9*c0cf5bddSBernard Metzler (See also RXE which is a similar software driver for RoCE.) 10*c0cf5bddSBernard Metzler 11*c0cf5bddSBernard Metzler The driver interfaces with the Linux RDMA stack and 12*c0cf5bddSBernard Metzler implements both a kernel and user space RDMA verbs API. 13*c0cf5bddSBernard Metzler The user space verbs API requires a support 14*c0cf5bddSBernard Metzler library named libsiw which is loaded by the generic user 15*c0cf5bddSBernard Metzler space verbs API, libibverbs. To implement RDMA over 16*c0cf5bddSBernard Metzler TCP/IP, the driver further interfaces with the Linux 17*c0cf5bddSBernard Metzler in-kernel TCP socket layer. 18
