Question about ftrace about gpu-dpdk

Question about ftrace about gpu-dpdk

It seems Nsight Systems default ftrace setting is not enough for tracing dpdk ​(under rx_pkt_burst/tx_pkt_burst).
For example, I want to monitor gdrcopy timing.

Is there any instruction?

@anikiforov can you please take a look at this?

It seems using rdma sniffer is one of solution. tcpdump can use this feature since libpcap 1.9 or later supports rdma sniffer.
