It enables a system with a12 standard Ethernet adapter to interoperate with a RoCE13 adapter or with another system running the RXE driver.14 Documentation on InfiniBand and RoCE can be downloaded at15 www.infinibandta.org and www.openfabrics.org. (See also16 siw which is a similar software driver for iWARP.)17 18 The driver is split into two layers, one interfaces with the19 Linux RDMA stack and implements a kernel or user space20 verbs API. The user space verbs API requires a support21 library named librxe which is loaded by the generic user22 space verbs API, libibverbs. The other layer interfaces23 with the Linux network stack at layer 3.24 25 To configure and work with soft-RoCE driver please use the26 following wiki page under "configure Soft-RoCE (RXE)" section:27 28 https://github.com/linux-rdma/rdma-core/blob/master/Documentation/rxe.md29
