Description
As passthrough logic filters incoming commands if they are not in the command information entries, filtering CSR usage is low. We could introduce the `filter` field in the CMD_INFO structure if a command needs to be processed internally but filtered in passthrough.
This way we can reduce 256bit CSR into 24 (# of CMD_INFO entries) bit.
