-  
-  This function is invoked when the PXE Base Code Protocol is about to transmit, has received,
-  or is waiting to receive a packet. Parameters Function and Received specify the type of event.
-  Parameters PacketLen and Packet specify the packet that generated the event. If these fields
-  are zero and NULL respectively, then this is a status update callback. If the operation specified
-  by Function is to continue, then CALLBACK_STATUS_CONTINUE should be returned. If the operation
-  specified by Function should be aborted, then CALLBACK_STATUS_ABORT should be returned. Due to
-  the polling nature of UEFI device drivers, a callback function should not execute for more than 5 ms.
-  The SetParameters() function must be called after a Callback Protocol is installed to enable the
-  use of callbacks.
-  
-  @param  This                  The pointer to the EFI_PXE_BASE_CODE_CALLBACK_PROTOCOL instance.
-  @param  Function              The PXE Base Code Protocol function that is waiting for an event.                                                              
-  @param  Received              TRUE if the callback is being invoked due to a receive event. FALSE if
-                                the callback is being invoked due to a transmit event.                
-  @param  PacketLen             The length, in bytes, of Packet. This field will have a value of zero if
-                                this is a wait for receive event.                                       
-  @param  Packet                If Received is TRUE, a pointer to the packet that was just received;
-                                otherwise a pointer to the packet that is about to be transmitted.  
-                                  
-  @retval EFI_PXE_BASE_CODE_CALLBACK_STATUS_CONTINUE if Function specifies a continue operation    
-  @retval EFI_PXE_BASE_CODE_CALLBACK_STATUS_ABORT    if Function specifies an abort operation
