Restore the SCBR device as an X68000 Host Bridge, including the Human68k-compatible host file-system service and the bridge-specific SCSI message handlers. Back its Ethernet path with the TAP driver, derive a stable locally administered MAC address, preserve the driver minimum-frame/FCS expectations, and restrict received traffic to its own unicast frames and broadcasts. Match the RASCTL/RASETHER/RASDRV bridge protocol that originated in the parent RaSCSI project: dispatch its non-standard message format on READ(10)/WRITE(10) (0x28/0x2a), with type, function, phase, and a three-byte byte count carried in the CDB. Advertise the legacy control channel required by RASCTL, translate its list and device-management commands to PiSCSI operations, and defer stop or system-shutdown requests until after the response is sent, while gating this insecure interface behind a new '-c disabled|media|full' runtime option. Preserve the type-1 Ethernet exchange used by RASETHER and the type-2, phased filesystem exchange used by RASDRV. Register the device in the factory, protobuf API, controller transfer path, command-line tooling, device listings, and web UI. Share the explicit bridge and proxy-ARP topology workflow with DaynaPort so both adapters validate and use the same mode/interface pair. Add build support for iconv where needed, extend unit coverage for device creation, RAS* protocol handling, CLI parsing, web attachment, and topology selection, and update the man pages and network-profile documentation for Host Bridge operation and its networking limits.
