9	This driver implements the InfiniBand RDMA transport over
10	the Linux network stack. It enables a system with a
11	standard Ethernet adapter to interoperate with a RoCE
12	adapter or with another system running the RXE driver.
13	Documentation on InfiniBand and RoCE can be downloaded at
14	www.infinibandta.org and www.openfabrics.org. (See also
15	siw which is a similar software driver for iWARP.)

17	The driver is split into two layers, one interfaces with the
18	Linux RDMA stack and implements a kernel or user space
19	verbs API. The user space verbs API requires a support
20	library named librxe which is loaded by the generic user
21	space verbs API, libibverbs. The other layer interfaces
22	with the Linux network stack at layer 3.
