-/**
- * 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
