[VTS_8.1]VtsHalDrmV1_0Target module test FAIL

[DESCRIPTION]

 测试VtsHalDrmV1_0Target单条或者多条fail

 这个module测试的关键因素就是需要高速稳定的翻墙网络

 遇到这个module,可以从device log看是否以下关键log:

05-17 01:48:03.840 32425 32425 D drm_hal_vendor_test@1.0: Running test DrmHalVendorDecryptTestCases/DrmHalVendorDecryptTest.AttemptDecryptWithKeysRemoved/0 from vendor module /data/local/tmp/32/lib/libvtswidevine.so

05-17 01:48:03.872 32425 32425 D : HTTP response(0):

或者：其他http错误码；

这基本可以肯定是网络状况问题，可以尝试ping一下log里显示fail的服务器，例如：

adb shell ping -c 10 widevine-proxy.appspot.com

敝司正常网络是没有丢包现象的，例如：
