    Source specific multicast with VMA

    sbob

      Hello!

       

      I'm currently working on an application that processes incoming multicast data and I have a Mellanox ConnectX-3 Ethernet adapter with VMA software package. The data that I work with is source specific and I have to use IP_ADD_SOURCE_MEMBERSHIP setsockopt() (not IP_ADD_MEMBERSHIP as it's written in the manual) while creating listening sockets. But it looks like VMA doesn't offload such type of traffic by default (or maybe at all). When I run vma_stats with -v 4 key it doesn't even show any membershib group that I subscribe to and vma_stats -p <pid> indicates that all traffic is routed through the OS.

       

      Does anybody know how to work this out?
