Should be: - drivers that has multicast support must have IFF_MULTICAST raised, and proper handling of multicast packets. - drivers that does not have multicast support, and that does have promisc mode support, should have IFF_MULTICAST raised, and set to PROMISC mode if more than one multicast address filter has set by SIOCADDMULTI. (It eats your CPU time, however, it enables you to accept multicast packets) - drivers that does not have multicast support nor promisc mode support, should have IFF_MULTICAST cleared. >How-To-Repeat: always. >Fix: If there's nobody working on it, I'll make some patches. Please drop me a note. Thanks. >Audit-Trail: >Unformatted:
