Configuring iWARP on Linux
Cavium 45000 Series Adapters support iWARP on the Linux Open Fabric
Enterprise Distributions (OFEDs) listed in
Table 7-1 on page 127 .
iWARP configuration on a Linux system includes the following:
 Installing the Driver
 Configuring iWARP and RoCE
 Detecting the Device
 Supported iWARP Applications
 Running Perftest for iWARP
 Configuring NFS-RDMA
 iWARP RDMA-Core Support on SLES 12 SP3 and RHEL 7.4
Installing the Driver
Install the RDMA drivers as shown in Chapter 3 Driver Installation .
Configuring iWARP and RoCE
To enable iWARP and RoCE:
1. Unload all FastLinQ drivers as follows:
# modprobe -r qedr or modprobe -r qede
2. Use the following command syntax to change the RDMA protocol by loading
the
qed
driver with a port interface PCI ID (
xx:xx.x
) and an RDMA
protocol value (
p
).
# modprobe -v qed rdma_protocol_map=<xx:xx.x-p>
The RDMA protocol (
p
) values are as follows:

0
—Accept the default (RoCE)

1
—No RDMA

2
—RoCE

3
—iWARP
