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