Plugin infrastructure improvements
This patch replaces requirement for vlib_plugin_register function in the plugin so file and introduces new macro: VLIB_PLUGIN_REGISTER () = { .version = "version string", .version_required = "requred version", .default_disabled = 1, .early_init = "early_init_function_name", }; Plugin will nor be loaded if .default_disabled is set to 1 unless explicitely enabled in startup.conf. If .verstion_required is set, plugin will not be loaded if there is version mismatch between plugin and vpp. This can be bypassed by setting "skip-version-check" for specific plugin. If .early-init string is present, plugin loader will try to resolve this specific symbol in the plugin namespace and make a function call. Following startup.conf configuration is added: plugins { path /path/to/plugin/directory plugin ila_plugin.so { enable skip-version-check } plugin acl_plugin.so { disable } } Change-Id: I706c691dd34d94ffe9e02b59831af8859a95f061 Signed-off-by: Damjan Marion <damarion@cisco.com>
