Is it possible to do ibdump live capture filtering as one can do with tcpdump? Is there a way to only capture RDMA Read and Write packets between a set of nodes performing MPI communications?
When dealing with FDR IB links, ibdump drops a lot of packets part of it because it attempts to capture every single packet on the links (such IPoIB packets, Subnet Manager datagrams, UD traffic,...). I'm aware of --mem-mode and --max-burst which can help reduce chances of packet drops.
