Hi Dave, The mlx5 driver code gets statically linked by the shared library in vpp-plugin-dpdk, so that's the package that needs to be updated. I'm not aware of a way to build just that one package, running 'make pkg-deb' will rebuild all of the VPP deb packages. Once they're built, you might be able to get by with only updating vpp-plugin-dpdk, but I recommend you update vpp, libvppinfra, vpp-plugin-core and vpp-plugin-dpdk just to avoid headaches.
I personally have not tried using the rdma plugin. I have heard other VPP devs recommend using it though. It's supposed to eliminate some processing overhead caused by differences between VPP's internal structure of a buffer and DPDK's, so it's possible that using an rdma interface would be more efficient than using a DPDK interface. And using the rdma plugin should not require rebuilding VPP for you to try it. This is the only doc I know of on using rdma interfaces - https://s3-docs.fd.io/vpp/22.10/developer/devicedrivers/rdma.html?highlight=rdma . -Matt On Thu, Jul 7, 2022 at 12:31 PM Dave Houser <davehous...@gmail.com> wrote: > Hi Matt, > > These are Mellanox ConnectX6 Nics. > > Looking at the logs more I found these two lines: > > ``` > > $vppctl show logs > > 2022/07/07 17:14:19:050 notice dpdk EAL init args: -c 2 -n 4 > --in-memory --no-telemetry --file-prefix vpp -a 0000:41:00.6 -a > 0000:41:01.6 --main-lcore 1 > > 2022/07/07 17:14:19:161 notice dpdk DPDK drivers found no > Ethernet devices... > ``` > > I just found this post > <https://lists.fd.io/g/vpp-dev/topic/87800334#20646> in the mailing list. > I assume this is my issue.
