/**
 * A package level call that causes all DataConnection bringUp calls to fail a specific
 * number of times. Here is an example that sets counter to 2 and cause to -3 for all instances:
 *    adb shell am broadcast -a com.android.internal.telephony.dataconnection.action_fail_bringup \
 *     --ei counter 2 --ei fail_cause -3
 *
 * Also you can add a suggested retry time if desired:
 *     --ei suggested_retry_time 5000
 *
 * The fail_cause is one of {@link DataFailCause}
