There are two methods to create new child interface for IPoIB. For a specific P_Key, write the desired P_Key to the create_child sysfs file: # echo 0x8000 > /sys/class/net/ib0/create_child This creates a new interface ib0.8000 operating with P_Key 0x8000. To create a new child interface on the default P_Key, its possible to use iproute: # ip link add link ib0 name ib0.1 type ipoib In order to create a new network namespace: # ip netns add ns1 Then, you can assign the new netdev to the namespace: # ip link set ib0.1 netns ns1 You can then set an IP address in the network namespace, and try some RDMA CM applications: # ip netns exec ns1 ip addr add dev ib0.1 192.168.0.1/24 # ip netns exec ns1 rdma_server Regards, Haggai -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
