2==================================
3
4This is how they currently behave, not what the hardware can do--for example,
5the Lance driver doesn't use its filter, even though the code for loading
6it is in the DEC Lance-based driver.

8The following are requirements for multicasting
9-----------------------------------------------
10AppleTalk Multicast hardware filtering not important but
11 avoid cards only doing promisc
12IP-Multicast Multicast hardware filters really help
13IP-MRoute AllMulti hardware filters are of no help

59PROMISC = This multicast mode is in fact promiscuous mode. Avoid using
60cards who go PROMISC on any multicast in a multicast kernel.
61
62(#) = Hardware multicast support is not used yet.
63(*) = Hardware support for Davicom 9132 chipset only.
