Notes from 2023-Mar-31 meeting on data-plane-modifiable per-table-entry state

[Andy Fingerhut]

The last slide of this deck has some brief notes I took from this meeting: https://docs.google.com/presentation/d/15vZJETWr0Cyht-dcQFnat28A3c9FoY7Z/edit?usp=sharing&ouid=113165450274035133953&rtpof=true&sd=true

I have started writing spec-like language in the form of an experimental PR in the P4_16 specification document here: Data plane writable per table entry state v1 by jafingerhut · Pull Request #1239 · p4lang/p4-spec (github.com)

One of the comments on that PR also contains the beginning of some notes on control plane API support for tables with data-plane-writable per-entry-table state.  See here: Data plane writable per table entry state v1 by jafingerhut · Pull Request #1239 · p4lang/p4-spec (github.com)

Comments, question, corrections all welcome on that, either in email here, or as additional comments on that PR.

The original 3-meeting series of invites is over, but participants agreed that for reviewing this proposed spec language, and discussing details of an experimental p4c implementation of this feature, additional meetings would be useful.

TODO: Andy to send out an invite for at least 2 more meetings on upcoming Fridays.

Regards,

Andy Fingerhut
