Yes, we are using Yocto for our basic kernel and OS binaries. >We also had a similar problem. In our case, the solution was to add the >firmware to the initramfs. That is one of my concerns as well, however, in my particular case, it seems that we were missing the default ddp configuration. Once this was added, the DPDK port now comes up. Thanks, Patrick
