1	Behaviour of Cards Under Multicast
2	==================================
3	
4	This is how they currently behave, not what the hardware can do--for example,
5	the Lance driver doesn't use its filter, even though the code for loading
6	it is in the DEC Lance-based driver.
7	
8	The following are requirements for multicasting 
9	-----------------------------------------------
10	AppleTalk	Multicast	hardware filtering not important but
11					 avoid cards only doing promisc
12	IP-Multicast	Multicast	hardware filters really help
13	IP-MRoute	AllMulti	hardware filters are of no help
14
