The following libraries are experimental, all of their functions can be changed or removed: - librte_bbdev - librte_bpf - librte_compressdev - librte_fib - librte_flow_classify - librte_graph - librte_ipsec - librte_node - librte_rcu - librte_rib - librte_stack - librte_telemetry Their status is properly announced in MAINTAINERS. Remind this status in their headers in a common fashion (aligned to ABI docs).
