+How to run this test
+
+edit linc config file. LINC-Switch/rel/linc/releases/1.0/sys.config
+You can find the sample config I used for the test below
+
+For this following config to work, the network interface
+linc-port and linc-port2 must be created before hand.
+(Or edit the port name depending on your environment)
+An easy way is to create them as follows
+# ip link add linc-port type veth peer name linc-port-peer
+# ip link set linc-port up
+# ip link add linc-port2 type veth peer name linc-port-peer2
+# ip link set linc-port2 up
+
+Then run linc
+# rel/linc/bin/linc console
+
+Then run ryu
+# PYTHONPATH=. ./bin/ryu-manager --verbose \
+        ryu/tests/integrated/test_of_config.py
+
+
+Here is my sys.config used for this test.
