No it is part of the same src package. > Yes, you need libmlx4, libmlx5 and libibverbs. > It is described in the doc: > http://doc.dpdk.org/guides/nics/mlx5.html#prerequisites Well that is the problem, we fulfill that prereq already. libmlx4, libmlx5 and libibverbs are installed by dependencies already and thought all the time that would be good enough. But we got told that we also need the package rdma-core [1] itself to be installed to be useful. That was a discussion with the subject "Please help us to verify DPDK 17.11.5 for Ubuntu 18.04/18.10" with Mellanox test people. Fortunately I keep you on CC on those - so maybe you can find it somewhere in your inbox and contact the other Mellanox people on that thread. After that you might help to translate their request into our terms please? The question is: a) what exactly is (binary package) rdma-core [1] needed for in that scenario b) if (a) would be generally true we wondered why it had to be a dep of the DPDK packages and not of e.g. libibverbs1 itself That is why we opened this bug for discussions [1]: https://packages.debian.org/sid/rdma-core
