0010 This driver implements the InfiniBand RDMA transport over
0011 the Linux network stack. It enables a system with a
0012 standard Ethernet adapter to interoperate with a RoCE
0013 adapter or with another system running the RXE driver.
0014 Documentation on InfiniBand and RoCE can be downloaded at
0015 www.infinibandta.org and www.openfabrics.org. (See also
0016 siw which is a similar software driver for iWARP.)
0017
0018 The driver is split into two layers, one interfaces with the
0019 Linux RDMA stack and implements a kernel or user space
0020 verbs API. The user space verbs API requires a support
0021 library named librxe which is loaded by the generic user
0022 space verbs API, libibverbs. The other layer interfaces
0023 with the Linux network stack at layer 3.
