+# Test script wrapper for running ODP pktio apps on linux-generic.
+#
+# For linux-generic the default behavior is to create two pairs of
+# virtual Ethernet interfaces and provide the names of these via
+# environment variables to pktio apps, the interfaces will be removed
+# before the script exits.
+#
+# Note that the creation of virtual Ethernet devices depends on having
+# CONFIG_VETH enabled in the kernel, if not enabled the env setup will be skipped.
