Callback function that is invoked when the PXE Base Code Protocol is about to transmit, has
received, or is waiting to receive a packet.
@param This 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
