| 7 | This driver implements the InfiniBand RDMA transport over | |
| 8 | the Linux network stack. It enables a system with a | |
| 9 | standard Ethernet adapter to interoperate with a RoCE | |
| 10 | adapter or with another system running the RXE driver. | |
| 11 | Documentation on InfiniBand and RoCE can be downloaded at | |
| 12 | www.infinibandta.org and www.openfabrics.org. (See also | |
| 13 | siw which is a similar software driver for iWARP.) | |
| 14 | ||
| 15 | The driver is split into two layers, one interfaces with the | |
| 16 | Linux RDMA stack and implements a kernel or user space | |
| 17 | verbs API. The user space verbs API requires a support | |
| 18 | library named librxe which is loaded by the generic user | |
| 19 | space verbs API, libibverbs. The other layer interfaces | |
| 20 | with the Linux network stack at layer 3. | |
