openwrt-dlink-dir842-r1: OpenWrt port informed by Realtek datapath research

openwrt-dlink-dir842-r1 ports OpenWrt to the D-Link DIR-842 R1 using a pinned base checkout and device-specific overlays. Its engineering notes investigate the RTL8197F and RTL8367S network path, switch setup and hardware NAT, while the build produces RAM-boot and NOR-flash firmware images.
