From 534667daec58ce8b2e417709e788934bea6f8f09 Mon Sep 17 00:00:00 2001 From: Matias Elo Date: Wed, 21 Feb 2018 17:19:12 +0200 Subject: linux-gen: add runtime configuration file Enables changing ODP runtime configuration options by using an optional configuration file (libconfig). Path to the conf file is passed using environment variable ODP_CONF_FILE. If ODP_CONF_FILE or a particular option is not set, hardcoded default values are used instead. An template configuration file is provided in config/odp-linux.conf. Runtime configuration is initially used by DPDK pktio to set NIC options. Adds new dependency to libconfig library.
