| 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 | |
| 15 | |
| 16 | Board Multicast AllMulti Promisc Filter |

| 59 | PROMISC = This multicast mode is in fact promiscuous mode. Avoid using |
| 60 | cards 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. |
