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.
