| 8 | This driver implements the InfiniBand RDMA transport over |
| 9 | the Linux network stack. It enables a system with a |
| 10 | standard Ethernet adapter to interoperate with a RoCE |
| 11 | adapter or with another system running the RXE driver. |
| 12 | Documentation on InfiniBand and RoCE can be downloaded at |
| 13 | www.infinibandta.org and www.openfabrics.org. (See also |
| 14 | siw which is a similar software driver for iWARP.) |
| 15 | |
| 16 | The driver is split into two layers, one interfaces with the |
| 17 | Linux RDMA stack and implements a kernel or user space |
| 18 | verbs API. The user space verbs API requires a support |
| 19 | library named librxe which is loaded by the generic user |
| 20 | space verbs API, libibverbs. The other layer interfaces |
| 21 | with the Linux network stack at layer 3. |
