donNewtonAlpha · PINS Working Group · web-flow · commit 24a64d65846d · 2021-12-01T08:53:15.000-08:00
* Orchagent: Integrate P4Orch
* support pushing switch configurations.
* support ACL table definitions.
* support insert/delete/modify in APPL_DB.
* support for L3 forwarding, WCMP, and ACL tables.
* support for response path through APPL_STATE_DB.
