It enables a system with a 128700e3e7SMoni Shoua standard Ethernet adapter to interoperate with a RoCE 138700e3e7SMoni Shoua adapter or with another system running the RXE driver. 148700e3e7SMoni Shoua Documentation on InfiniBand and RoCE can be downloaded at 158700e3e7SMoni Shoua www.infinibandta.org and www.openfabrics.org.

The user space verbs API requires a support 218700e3e7SMoni Shoua library named librxe which is loaded by the generic user 228700e3e7SMoni Shoua space verbs API, libibverbs. The other layer interfaces 238700e3e7SMoni Shoua with the Linux network stack at layer 3. 248700e3e7SMoni Shoua 258700e3e7SMoni Shoua To configure and work with soft-RoCE driver please use the 268700e3e7SMoni Shoua following wiki page under "configure Soft-RoCE (RXE)" section: 278700e3e7SMoni Shoua 28a1c5dd13SLeon Romanovsky https://github.com/linux-rdma/rdma-core/blob/master/Documentation/rxe.md 29
