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