Thanks for the response, Philip!
I can get the dumps, they just don't look too pretty and tcpdump doesn't seem to understand the RoCE traffic. I was hoping to just get timestamps on each RDMA transfer to get more latency insight. I might grab the unstable build of Wireshark, like you suggested, to see if that can give me what I'm looking for.
Thanks again,
Curt

Indeed, the unstable version of Wireshark worked great to decode the dumps for me on a Mac. Thanks promanov
