[p4rs, codegen] Pipeline::clear_table_entries, + helios CI bump - #278
Merged

Conversation
When dpd restarts against a running softnpu pipeline, previous table entries persist, even though the daemon does not know what the keys are. `Pipeline` had support for add/remove by key and a dump command, but there was no generic way to empty tables. This work adds a `clear_table_entries(table_id)` to the trait. In codegen, we now emit a `clear_<qtfn>_entries` per table alongside the add/remove/get ones. With this change in place, softnpu can use it for a write-only `TableClear` management message, so that dendrite's SoftNPU `TableOps::clear` can be un-stubbed. Includes: - [ci] s/helios-2.0/helios-3.0/ matching other networking repos.

Nice, I see you've also added a bool to show if the table exists.
