Added the release version that experimental API is added as comment in next-net,
like following:
+++ b/lib/librte_vhost/version.map
@@ -76,4 +76,7 @@ EXPERIMENTAL {
rte_vhost_async_channel_unregister;
rte_vhost_submit_enqueue_burst;
rte_vhost_poll_enqueue_completed;
+
+ # added in 21.05
+ rte_vhost_get_negotiated_protocol_features;
};
We are doing this already in many libraries [1], this helps us easily observe
how long an API is staying as experimental in a library.
