1 | Behaviour of Cards Under Multicast |
| 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 | ||

| 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. |
