	/* Note
	-------
	 * WinDis 32 V5.00.10.31 introduced a mechanism which provides
	 * a simple way to accomodate media which has packet data lengths
	 * larger then the 1500 bytes used by Ethernet.
	 *
	 * To suport this, the PacketBuffer field in the W32N_PACKET structure
	 * was changed from having a fixed length of:
	 *
	 *   (2*ETHER_ADDR_LENGTH) + ETHER_TYPE_LENGTH + MAX_ETHER_SIZE + 2
	 *
	 * to having a placeholder length of one (1) byte. This mechanism
	 * requires that additional memory for the actual buffer must be
	 * provided contiguous to and immediately following the placeholder
	 * PacketBuffer field.
	 *
	 *		// ATTENTION!!! Above not currently correct!!!
	 *		// Hardcoded to 4550 Bytes...
	 *
	 * Although there are other ways to fulfill this requirement, this
	 * test application simply provides the PacketBufferSpace character
	 * array immediately following the UserPacketData field.
	 *
	 * The Padding field accounts for the possibility that a compiler may
	 * do something funny.
