| 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. |
