+ * This means we should try to be fairly precise about transport and

* If the request has more than one transport or capability it doesn't
* match the old legacy requests (they selected only single transport/capability)
* so this function cannot map the request to a single legacy type and
* the resulting network will not be available to the legacy APIs.
*
+ * This code is only called from the requestNetwork API (L and above).
+ *
+ * Setting a legacy type causes CONNECTIVITY_ACTION broadcasts, which are expensive

+ * do this for SUPL requests, which are the only ones that we know need it. If

* TODO - This should be removed when the legacy APIs are removed.
