> Hi All,
> 
> During recent work on the DPDK ABI, where we are looking to develop a nightly ABI regression test. 
> 
> We found a large number of experimental functions currently in DPDK API.
> Currently, there are 537 experimental APIs out of a total of roughly ~1800 API, 30%-ish. 
> 
> While there is no correct number, as a percentage of the total, this appears to be very high.
> I would question if all these API are really "new" and warrant the status?
> 
> There are currently 38 libraries and drivers with experimental functions.
> And to be fair there are number of recently added libraries in list, shown below.
> However there are also a number of libraries that have been around a very long time.
> 
> The following libraries and drivers have 10 or more experimental functions:
> 
> 1.	rte_eal: 119
> 2.	rte_ethdev: 43
> 3.	rte_vhost: 42
> 4.	rte_graph: 35 (EXPERIMENTAL)
> 5.	rte_compressdev: 34
> 6.	rte_rib: 28 (EXPERIMENTAL)
> 7.	rte_pipeline: 24
> 8.	rte_regexdev: 22 (EXPERIMENTAL)
> 9.	rte_cryptodev: 18
> 10.	rte_fib: 16 (EXPERIMENTAL)
> 11.	rte_ipsec: 15 (EXPERIMENTAL)
> 12.	rte_telemetry: 12 (EXPERIMENTAL)
> 13.	rte_mbuf: 11
> 14.	rte_rcu: 11 (EXPERIMENTAL)
> 15.	rte_bus_fslmc: 11
> 16.	rte_bpf: 10 (EXPERIMENTAL)
> 
> Do the maintainers of these libraries and drivers, 
> A. Feel that experimental status continues to be warranted against these API?
> B. Have plans in place to move all/some of these functions to stable in the 20.11 timeframe?
> 
> Kudos to Conor Walsh for pulling this data together. 

Do you have a tool to sort experimental functions per age?
