29/**
30 * A package level call that causes all DataConnection bringUp calls to fail a specific
31 * number of times. Here is an example that sets counter to 2 and cause to -3 for all instances:
32 *    adb shell am broadcast -a com.android.internal.telephony.dataconnection.action_fail_bringup \
33 *     --ei counter 2 --ei fail_cause -3
34 *
35 * Also you can add a suggested retry time if desired:
36 *     --ei suggested_retry_time 5000
37 *
38 * There is also a per DC command implemented in {@link DcRetryAlarmController#mFailBringUp} the intent is
39 * the same as above except the action has a "DC-x" before the action_fail_bringup so for
40 * DC-1 the action action is:
41 *    adb shell am broadcast \
42 *      -a com.android.internal.telephony.dataconnection.DC-1.action_fail_bringup \
43 *      --ei counter 2 --ei fail_cause -3
44 *
45 * The fail_cause is one of {@link DcFailCause}
