| This driver implements the iWARP RDMA transport over | |
| the Linux TCP/IP network stack. It enables a system with a | |
| standard Ethernet adapter to interoperate with a iWARP | |
| adapter or with another system running the SIW driver. | |
| (See also RXE which is a similar software driver for RoCE.) | |
| The driver interfaces with the Linux RDMA stack and | |
| implements both a kernel and user space RDMA verbs API. | |
| The user space verbs API requires a support | |
| library named libsiw which is loaded by the generic user | |
| space verbs API, libibverbs. To implement RDMA over | |
| TCP/IP, the driver further interfaces with the Linux | |
| in-kernel TCP socket layer. |
