Behaviour of cards under Multicast. This is how they currently=20
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=09Multicast=09hardware filtering not important but
=09=09=09=09 avoid cards only doing promisc
IP-Multicast=09Multicast=09hardware filters really help

PROMISC =3D This multicasts mode is in fact promiscuous mode. Avoid using
cards who go PROMISC on any multicast in a multicast kernel.
(#) =3D Hardware multicast support is not used yet.
Hope this is of some use to you.
