Behaviour of cards under Multicast. This is how they currently
behave not what the hardware can do. In particular all the 8390 based
cards don't use the onboard hash filter, and the lance driver doesn't
use its filter, even though the code for loading it is in the DEC
lance based driver.
The following multicast requirements are needed
-----------------------------------------------
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
