  1. Behaviour of Cards Under Multicast
    2. 

  2. ==================================
    3. 

  3. 

  4. This is how they currently behave, not what the hardware can do--for example,
    5. 

  5. the Lance driver doesn't use its filter, even though the code for loading
    6. 

  6. it is in the DEC Lance-based driver.
    7. 

  7. 

  8. The following are requirements for multicasting 
    9. 

  9. -----------------------------------------------
    10. 

  10. AppleTalk	Multicast	hardware filtering not important but
    11. 

  11. 				 avoid cards only doing promisc
    12. 

  12. IP-Multicast	Multicast	hardware filters really help
    13. 

  13. IP-MRoute	AllMulti	hardware filters are of no help
    14. 

  14. 

  15. 

  16. Board		Multicast	AllMulti	Promisc		Filter
