Configuring iWARP on Linux
Marvell 41xxx 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
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>
NOTE
This procedure applies only if you previously selected iWARP+RoCE as the
value for the RDMA Protocol Support parameter during preboot
configuration using HII (see Configuring NIC Parameters, Step 5 on
page 51).
