Chapter V. WD-UDP

If you have eth2 and eth3 configured for example, you can define certain endpoints to eth2 and

others to eth3:

endpoint {interface=eth2 port=9999}

endpoint {interface=eth3 port=8888}

For VLAN support, create your VLANs using the normal OS service (like vconfig, for example),

then add entries to define the VLAN and priority for each endpoint to be accelerated:

endpoint {interface = eth2.5 port=10000}

endpoint {interface = eth2.7 priority=3 port=9000}

For Jumbo Frames of 9000B, follow the steps mentioned below:

[root@host]# echo 1024 > /proc/sys/vm/nr_hugepages

[root@host]# CXGB4_SOCK_HUGE_PAGES=1 wdload <pathto>/your_application

4.1.3. Using per process config file

The libcxgb4_sock library utilizes the Linux RDMA Verbs subsystem, and thus requires the

RDMA modules be loaded. Ensure that your systems load the iw_cxgb4 and rdma_ucm

modules:

[root@host]# modprobe iw_cxgb4

[root@host]# modprobe rdma_ucm

For individual interfaces, create a config file for 

[root@host]# cat /root/config1

endpoint {interface=eth1 port=0}

 Jumbo frames of 9000B are supported only on kernel 2.6.32 and above.

 In order to offload IPv6 UDP sockets, please select “low latency

networking” as T4 configuration tuning option during installation.
