vlib: add plugin override support
Allow a plugin to override (suppress loading of) other plugins. This mechanism allows a developer to prevent specific plugins from being loaded. To do so, provide an "overrides" list in the plugin definition: VLIB_PLUGIN_REGISTER () = { <snip> .overrides = "avf_plugin.so,ioam_plugin.so,dpdk_plugin.so", }; or some such. Simply list the plugins in question as shown above. The .overrides structure member is limited to 256 octets. The named .elf section mechanism used to discover the vlib_plugin_registration_t's precludes the use of a variable-length array of strings. Use the vlib log to eliminate plugin and built-in vat plugin loader console spew. Added vlib_log_register_class_rate_limit(...) to allow procedural configuration of the log rate-limit. We *never* want to rate-limit plugin loader messages. Type: feature Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I0a9327b8cf5508482f057342783252112cb44170
