3dec9fcdd56adf1b4a563137b4915c8f2d83b881qs * functionality (below) must also be used to provide the packet

3dec9fcdd56adf1b4a563137b4915c8f2d83b881qs * stopped and be queued, but no packets would be dropped. Thus,
3dec9fcdd56adf1b4a563137b4915c8f2d83b881qs * the VMAC can only be enabled/disabled at packet boundary. The
