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