It enables a system with a 118700e3e7SMoni Shoua standard Ethernet adapter to interoperate with a RoCE 128700e3e7SMoni Shoua adapter or with another system running the RXE driver. 138700e3e7SMoni Shoua Documentation on InfiniBand and RoCE can be downloaded at 148700e3e7SMoni Shoua www.infinibandta.org and www.openfabrics.org.

The user space verbs API requires a support 208700e3e7SMoni Shoua library named librxe which is loaded by the generic user 218700e3e7SMoni Shoua space verbs API, libibverbs. The other layer interfaces 228700e3e7SMoni Shoua with the Linux network stack at layer 3. 238700e3e7SMoni Shoua 248700e3e7SMoni Shoua To configure and work with soft-RoCE driver please use the 258700e3e7SMoni Shoua following wiki page under "configure Soft-RoCE (RXE)" section: 268700e3e7SMoni Shoua 27a1c5dd13SLeon Romanovsky https://github.com/linux-rdma/rdma-core/blob/master/Documentation/rxe.md 28
