It enables a system with a 9 standard Ethernet adapter to interoperate with a RoCE 10 adapter or with another system running the RXE driver. 11 Documentation on InfiniBand and RoCE can be downloaded at 12 www.infinibandta.org and www.openfabrics.org. (See also 13 siw which is a similar software driver for iWARP.) 14 15 The driver is split into two layers, one interfaces with the 16 Linux RDMA stack and implements a kernel or user space 17 verbs API. The user space verbs API requires a support 18 library named librxe which is loaded by the generic user 19 space verbs API, libibverbs. The other layer interfaces 20 with the Linux network stack at layer 3. 21 22 To configure and work with soft-RoCE driver please use the 23 following wiki page under "configure Soft-RoCE (RXE)" section: 24 25 https://github.com/linux-rdma/rdma-core/blob/master/Documentation/rxe.md 26
