atm_qos struct should be the same both for user and kernel spaces. Via the __SO_ENCODE() macro it is used to define the SO_ATMQOS socket IOC. During the VRX518 support introduction, the atm_trafprm sturct nested into the atm_qos stucture was update with newer fields that are referenced by the ATM TC layer of the VRX518 TC driver. These new fields are intended to communicate information for extra traffic classes supported by the driver. But we are still using vanilla kernel headers to build the toolchain. Due to the atm.h header incoherency br2684ctl from linux-atm tools is incapable to configure the ATM bridge netdev: br2684ctl: Interface "dsl0" created sucessfully br2684ctl: Communicating over ATM 0.1.2, encapsulation: LLC br2684ctl: setsockopt SO_ATMQOS 22 <-- EINVAL errno br2684ctl: Fatal: failed to connect on socket; File descriptor in bad state There are two options to fix this incoherency. (a) update the header file in the toolchain to build linux-atm against updated atm_trafprm and atm_qos structures, or (b) revert atm_trafprm changes. Since there are no actual users of the extra ATM QoS traffic classes, just drop these extra traffic classes from vrx518_tc ATM TC layer and drop the kernel patch updating atm.h. Besides fixing the compatibility with linux-atm tools, removing the kernel patch should simplify kernel updates removing unneeded burden of maintenance. Run tested with FRITZ!Box 7530 with disabled extra traffic classes and then removed them entirely before the submission.

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 python3.7+ rsync subversion unzip which
Quickstart
-
Run
./scripts/feeds update -a
to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -a
to install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfig
to select your preferred configuration for the toolchain, target system & firmware packages. -
Run
make
to 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.
