The Otto SoCs reach most of their switch state through indirect table access: a command word carrying table, index and direction goes into one register, and the entry itself appears in a window of data registers. That mechanism is not layer 2 and has no natural home in a DSA driver; it sits in common.c only because DSA happens to be its first consumer. Move the descriptor array, struct table_reg and the rtl_table_* functions verbatim into table.c and table.h. Nothing is renamed and no line of the implementation changes; rtl-otto.h includes the new header, so every consumer compiles unchanged. The consumers already called these symbols externally, so relocating the definitions only moves them from common.o to table.o. Built for realtek/rtl930x before and after: rtl838x.o, rtl839x.o, rtl930x.o, rtl931x.o and l3.o are identical once debug sections are stripped, and common.o loses 1536 bytes of code and data, 1004 of text and 532 of data. The raw objects do differ, because CONFIG_DEBUG_INFO records line numbers from rtl-otto.h.

OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.

Download
Built firmware images are available for many architectures and come with a package selection to be used as WiFi home router. To quickly find a factory image usable to migrate from a vendor stock firmware to OpenWrt, try the Firmware Selector.
If your device is supported, please follow the Info link to see install instructions or consult the support resources listed below.
An advanced user may require additional or specific package. (Toolchain, SDK, ...) For everything else than simple firmware download, try the wiki download page:
Development
To build your own firmware you need a GNU/Linux, BSD or macOS system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.
Requirements
You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.
binutils bzip2 diff find flex gawk gcc-6+ getopt grep install libc-dev libz-dev
make4.1+ perl python3.8+ rsync subversion unzip which
Quickstart
-
Run
./scripts/feeds update -ato obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -ato install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfigto select your preferred configuration for the toolchain, target system & firmware packages. -
Run
maketo build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.

different categories. All packages are installed via the OpenWrt package
manager called opkg. If you're looking to develop the web interface or port
packages to OpenWrt, please find the fitting repository below.
