I was just thinking about indicating in the Linux starting guide that the DPDK environment can be configured in some system files. While I see the benefit of such configuration, I am not sure we should configure the DPDK itself. We could have several applications using DPDK with different configurations. Do you think you could rework it in a way it can be integrated by applications in their own configuration? More opinions from users and integrators would be welcome here.
