ppe_mac_hw_init() enables the loopback, waits 100 ms for it and opens that
port's PPE_PORT_BRIDGE_CTRL_TXMAC_EN, the gate the fabric needs before it
will hand a port a frame. Two paths shut it again. qca_ppe_setup() walks
every port and clears the bit for all but the CPU port, and the loopback
port is described by no board, so DSA also sees it as unused and calls
port_disable() on it. Nothing reopens it: the port has no phylink, so no
link event ever runs, and the loopback probe configured stays unreachable
for the life of the boot.
Give the bit one owner. ppe_port_bridge_txmac_set() refuses to close the
loopback port's gate, and the setup walk stops writing the bit at all - it
was only ever setting it for the CPU port, whose gate qca_ppe_port_enable()
opens a moment later when DSA enables that port. A user port's gate is
still opened by qca_ppe_mac_link_up() and closed by its link going down.
Tested on IPQ8074 (Xiaomi AX3600, kernel 6.18.44): PPE_PORT_BRIDGE_CTRL(7)
reads 0x0002ff08 before this change and 0x0003ff08 after it, the two
differing only in TXMAC_EN. The CPU port and the four user ports read the
bit set and the two ports no board describes read it clear. Forwarding,
offload and dmesg are unchanged.

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.
Sunshine!
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.
Related Repositories
The main repository uses multiple sub-repositories to manage packages of
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.
