Version 3 adds support for "source filtering", that is, the ability for a system to report interest in receiving packets *only* from specific source addresses, as required to support Source-Specific Multicast [SSM], or from *all but* specific source addresses, sent to a particular multicast address. Version 3 is designed to be interoperable with Versions 1 and 2. Therefore, it will add more complexity to track down all the specific sources for each port. I'd rather leave that to after this series and RCUify. fbl _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
