+* This testcase uses the libnetns.c from the lib to create network NS1.
+* In libnetns.c it uses 2 scripts parentns.sh and childns.sh to create this.
+*
+* This testcase creates Network-NS NS1 and renames the net-dev of NS1 to veth4.
+* Then it kills the Network-NS, and checks the contents of parent sysfs.
+* The system should remain stable and also checks sysfs contents of parent NS.
+* It returns PASS on Success else returns FAIL.
+*
+* Scripts used: parentns.sh, childns.sh , delchild.sh rename_net.sh
