Hello Amir and thanks for this bug report. Dann identified a fix and forwarded it to Debian [1]. It is best if the change lands in Debian so Debian and other downstream distros will also benefit for the change, and Ubuntu developers won't have to maintain a delta.

We'd like users of rdma devices to be able to sniff on them using stock tcpdump. Currently when using default tcpdump It does not list rdma devices. $ tcpdump -D |grep -i rdma $ when using locally build tcpdump (with rdma enabled) $ cd <tcpdump source folder> $ ./tcpdump -D |grep -i rdma 24.rocep4s0 (RDMA sniffer) 25.rocep7s0f0 (RDMA sniffer) 26.rocep7s0f1 (RDMA sniffer) 27.rocep10s0f0 (RDMA sniffer) 28.rocep10s0f1 (RDMA sniffer) 29.rocep33s0f0 (RDMA sniffer) 30.rocep33s0f1 (RDMA sniffer) 31.rocep36s0f0 (RDMA sniffer) 32.ibp36s0f1 (RDMA sniffer) Locally build steps: clone sources: $ mkdir tcpdumpbuild $ cd tcpdumpbuild/ $ git clone https://github.com/the-tcpdump-group/tcpdump.git $ git clone https://github.com/the-tcpdump-group/libpcap.git install required packages (including rdma packages so libpcap is built with rdma enabled): $ apt install flex bison librdmacm-dev librdmacm1 rdma-core rdmacm-utils configure and build $ cd libpcap $ ./autogen.sh $ ./configure --enable-rdma=yes $ make cd ../tcpdump/ ./autogen.sh ./configure $ make now ./tcpdump -D can show rdma devices.
