Currently the sidecar for the D simulator in P-D scenario should be configured to use nixl connector, in this case it works with additional fields in the request/response (do_remote_decode, do_remote_prefill, remote_block_ids, remote_engine_id, remote_host, remote_port)

Current version of sidecar uses nixl2 connector which expects for the following fields:

• kv_transfer_params
  • do_remote_decode
  • do_remote_prefill
  • remote_engine_id
  • remote_block_ids
  • remote_host
  • remote_port
