Based on the discussion in below mail thread, it is concluded that
all traffic manager API's (rte_tm.h) need to be marked experimental
till few more releases to support further improvements to spec.

Adding deprication notice for the same in advance.

Slightly wordy - suggest making it a small bit more concise as follows. 

* traffic manager: All traffic manager API's in ``rte_tm.h`` were mistakenly made 
 abi stable in the v19.11 release. The TM maintainer and other contributor's have 
 agreed to keep the TM API's as experimental in expectation of additional spec 
 improvements. Therefore, all API's in ``rte_tm.h`` will be marked back as 
 experimental in v20.11 DPDK release. For more detail, please see `the thread
 <https://mails.dpdk.org/archives/dev/2020-April/164970.html>`_.

Hi Nithin Kumar,

Perhaps there was a misunderstanding, the paragraph in the deprecation note
documents about making tm APIs experimental needs to be removed, since it won't
be valid anymore after this patch.
And best place to remove that note is this patch.

As discussed earlier and agreed by TM and Ethdev maintainers, __rte_experimental tag was introduced several
releases after TM spec was added and TM spec remained untouched ending up making it stable unintentionally. 

Bruce and other maintainers pointed out that we cannot fix it as a "Fixes:" patch in order
to honor ABI commitments, and suggestion was to change the complete spec back to
experimental in next ABI change window and proceed with improvements that make
it stable API in subsequent releases.

We discussed it I agree, but to identify how this happened.
I am not sure we all agreed it was ok to give a blanket EXPERIMENTAL. 

This API has been largely unchanged for 3 years.
How can we justify keeping EXPERIMENTAL without a specific reason?
Can you be more specific about planned changes?

Basically the changes atleast which initiated this discussion were

#1 Support to configure shaper in pkt mode that helps ratelimiting in
PPS(Packets per Sec) as opposed to BPS(Bits per Sec).
Needs change to a lot of existing tm param and capability structs.

#2 Support dynamic offload flags based Tx offload for tm packet marking.

#3 Support TM node color stats that report per tm color(red, green, yellow) pkt stats.

All the above three changes though add significant features and doesn't break existing
PMD's.

Applied to dpdk-next-net/main, thanks.


I see there is discussion on the experimental status of the APIs, I am

incrementally on top of this.
