* This function is idempotent: It may be called numerous times. The
* initialization will be performed only on the first time that it is
* called. Therefore, it may be called during packet radio driver
* initialization, even if there are multiple packet radio drivers.

* list. If that the list is empty, then the meta-data structure will be
* allocated from the dynamic memory pool.

* Input Parameters:

* Returned Value:
