ODP configuration options
-------------------------

Runtime configuration options can be passed to an ODP instance by
setting ODP_CONFIG_FILE environment variable to point to a libconfig
format configuration file. A template configuration file with default
values is provided in config/odp-linux-generic.conf. The values set in
config/odp-linux-generic.conf are hardcoded during configure/build
phase. If ODP_CONFIG_FILE is not set at runtime, hardcoded default
values are used instead of any configuration file. A configuration file
passed using ODP_CONFIG_FILE doesn't have to include all available
options. The missing options are replaced with hardcoded default values.
