+Routine Description:
+
+ TpInitMedia initializes the media data structure with information
+ specific to the media type that will be test on. The information
+ descibes the size of various elements of a packet for the media in
+ question, and is used when creating and destroying packets, etc.
+
+Arguments:
+
+ MediumType - the specific NDIS Media that is being used in this test.
+
+Return Value:
+
+ PTP_MEDIA_INFO - a pointer to the media information structure for
+ the Media being used in this test.
