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. 22 23 To configure and work with soft-RoCE driver please use the 24 following wiki page under "configure Soft-RoCE (RXE)" section: 25 26 https://github.com/linux-rdma/rdma-core/blob/master/Documentation/rxe.md 27
