Description
The dpd daemon expects that it can clear ASIC table state at startup. However, the softnpu TableOps implementation does not implement this:
This can lead to unpredictable behavior as noted in oxidecomputer/maghemite#545.

Research direction
Start in asic/src/softnpu/table.rs at the TableOps implementation around lines 104–107 and determine how clear is expected to reset ASIC table state. Check how the dpd daemon invokes clearing at startup, then verify that the softnpu implementation leaves the tables clear and avoids the unpredictable behavior described in oxidecomputer/maghemite#545.
