Importance or Severity

High

Description of the bug

SmartSwitch DPU gNOI calls require metadata headers such as target type/index. The helper stack did not propagate metadata through PtfGnoi and PtfGrpc.

Affected APIs:

PtfGnoi.system_time
PtfGnoi.file_transfer_to_remote
PtfGnoi.system_set_package
PtfGrpc.call_unary
PtfGrpc.call_client_streaming

Steps to Reproduce

Run full SmartSwitch DPU+NPU gNOI upgrade.

Actual Behavior and Expected Behavior

Actual:
DPU routed calls fail with errors like:

TypeError: PtfGnoi.system_time() got an unexpected keyword argument 'metadata'

Expected:
All gNOI helper calls should accept and forward metadata as grpcurl -H headers.
