If RoCE and you have a switch in the middle, you can probably run wireshark/tcpdump there. If you are using a driver that implements the right flow steering API you could use libpcap: https://github.com/the-tcpdump-group/libpcap The APIs used: https://github.com/the-tcpdump-group/libpcap/blob/master/pcap-rdmasniff.c > > > Thank you. > > Dimitris > Mark
