+/**
+ * Tests for the VpnService API.
+ *
+ * These tests establish a VPN via the VpnService API, and have the service reflect the packets back
+ * to the device without causing any network traffic. This allows testing the local VPN data path
+ * without a network connection or a VPN server.
+ *
+ * Note: in Lollipop, VPN functionality relies on kernel support for UID-based routing. If these
+ * tests fail, it may be due to the lack of kernel support. The necessary patches can be
+ * cherry-picked from the Android common kernel trees:
+ *
+ * android-3.10:
+ * https://android-review.googlesource.com/#/c/99220/
+ * https://android-review.googlesource.com/#/c/100545/
+ *
+ * android-3.4:
+ * https://android-review.googlesource.com/#/c/99225/
+ * https://android-review.googlesource.com/#/c/100557/
+ *
+ * To ensure that the kernel has the required commits, run the kernel unit
+ * tests described at:
+ *
+ * https://source.android.com/devices/tech/config/kernel_network_tests.html
