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.)

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.
