Title: P4 Arch Design WG
Dear all,

Venues rotate between Barefoot, Cisco and Google.

Paradera conference room, 3rd floor
Cisco Building 6
375 East Tasman Drive
San Jose, CA 95134

Enter the lobby at the front of the building (the side facing Tasman  
Drive), where the lobby ambassador will give you a visitor’s badge, and  
either I or another Cisco employee will direct you to the meeting room,  
which is the Paradera conference room on the 3rd floor.

There are visitor parking spots close to the building, but you should be  
able to park anywhere you can find a free spot other than the blue  
handicapped spots (unless you qualify for those, of course).


Bridged metadata (Han, Andy) 45 min:
     - https://github.com/p4lang/p4-spec/issues/404
     - Proposal for metadata packing and unpacking  
We would really like to bring this issue closer to resolution. Please read  
and think about the example program attached  
https://github.com/p4lang/p4-spec/issues/453#issuecomment-341327037, in  
terms of programmer convenience, and writing a compiler to do it.

Action Profiles (Samar) 15 min:
     - Added max_groups attribute to action selector  
     - Fungibility of action selector size  
     - Document interaction between direct counters/meters and action  
profile/selector https://github.com/p4lang/p4-spec/issues/466

Naming (Calin) 15 min:
     - PSA table property names https://github.com/p4lang/p4-spec/pull/481
     - Consistent naming conventions  

Miscellaneous (all) 15 min:
     - State of direct meters and counters when entries are added and  
removed https://github.com/p4lang/p4-spec/issues/359
     - Should InternetChecksum() extern be guaranteed initialized as if  
clear() was called? https://github.com/p4lang/p4-spec/issues/458
     - Is drop allowed in egress? (only remaining issue is I think creating  
an example suggested by Samar Abdi)  
     - Using virtual functions to specify action chosen in action_selector  
     - Document effect of multiple pipelines on PSA  

Ports (saved for a later discussion)
     - PortId_t type: https://github.com/p4lang/p4-spec/issues/370
     - CPU port semantics https://github.com/p4lang/p4-spec/issues/321
