   Wording quibble.  Given the loaded nature of the word "broadcast" it   
   might be better to put that as "frames get transmitted out all   
   connected ports" or "frames get flooded out all connected ports" lest   
   some new folks think the frames get transformed into actaul broadcast   
   frames.
