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
|
