Hi, I was going through the mlx4 code and noticed that this function mlx4_SET_MCAST_FLTR calls the mlx4_SET_MCAST_FLTR_wrapper which in turns has an empty body. So, I was just wondering if the multicast filtering functionality is disabled? Is QP_ATTACH the replacement for this? Couldn't understand so wanted your help on this...
