  10        This driver implements the InfiniBand RDMA transport over
  11        the Linux network stack. 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.
