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