It enables a system with a 11 standard Ethernet adapter to interoperate with a RoCE 12 adapter or with another system running the RXE driver. 13 Documentation on InfiniBand and RoCE can be downloaded at 14 www.infinibandta.org and www.openfabrics.org. (See also 15 siw which is a similar software driver for iWARP.) 16 17 The driver is split into two layers, one interfaces with the 18 Linux RDMA stack and implements a kernel or user space 19 verbs API. The user space verbs API requires a support 20 library named librxe which is loaded by the generic user 21 space verbs API, libibverbs. The other layer interfaces 22 with the Linux network stack at layer 3. 23 24 To configure and work with soft-RoCE driver please use the 25 following wiki page under "configure Soft-RoCE (RXE)" section: 26 27 https://github.com/linux-rdma/rdma-core/blob/master/Documentation/rxe.md 28
