  Behaviour of Cards Under Multicast
  ==================================
  
  This is how they currently behave, not what the hardware can do--for example,
  the Lance driver doesn't use its filter, even though the code for loading
  it is in the DEC Lance-based driver.
  
  The following are requirements for multicasting 
  -----------------------------------------------
  AppleTalk	Multicast	hardware filtering not important but
  				 avoid cards only doing promisc
  IP-Multicast	Multicast	hardware filters really help
  IP-MRoute	AllMulti	hardware filters are of no help
  
  
  Board		Multicast	AllMulti	Promisc		Filter

  PROMISC = This multicast mode is in fact promiscuous mode. Avoid using
  cards who go PROMISC on any multicast in a multicast kernel.
  
  (#) = Hardware multicast support is not used yet.
  (*) = Hardware support for Davicom 9132 chipset only.
