3 tristate "Software RDMA over Ethernet (RoCE) driver"
4 depends on INET && PCI && INFINIBAND
5 depends on !64BIT || ARCH_DMA_ADDR_T_64BIT
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.
