The r39147 commit introduces a regression: at lease on some routers with ar8216 switch large packets get lost if 802.1q tagged port is used on the interface connected to the aforementioned switch. The r39147 changes code in the way so interface is set to accept packets no longer than max ethernet frame length for a given mtu. Unfortunately ar8216 has a feature: it sends two additional bytes as a packet header and those this header needs to be added to the max frame length. Otherwise long enough packets get lost. The problem only manuifests itself if interface is used in vlan tagged mode. If interface is untagged then ar8216's header fits into space used by 802.1q tag and not packets are lost. Include two additional bytes in the max frame length calculation to fix the issue. This patch is tested and works with Trendnet TEW-632BRP.

This is the buildsystem for the OpenWrt Linux distribution. Please use "make menuconfig" to configure your appreciated configuration for the toolchain and firmware. You need to have installed gcc, binutils, bzip2, flex, python, perl make, find, grep, diff, unzip, gawk, getopt, libz-dev and libc headers. Run "./scripts/feeds update -a" to get all the latest package definitions defined in feeds.conf / feeds.conf.default respectively and "./scripts/feeds install -a" to install symlinks of all of them into package/feeds/. Use "make menuconfig" to configure your image. Simply running "make" will build your firmware. It will download all sources, build the cross-compile toolchain, the kernel and all choosen applications. You can use "scripts/flashing/flash.sh" for remotely updating your embedded system via tftp. The OpenWrt system is documented in docs/. You will need a LaTeX distribution and the tex4ht package to build the documentation. Type "make -C docs/" to build it. To build your own firmware you need to have access to a Linux, BSD or MacOSX system (case-sensitive filesystem required). Cygwin will not be supported because of the lack of case sensitiveness in the file system. Sunshine! Your OpenWrt Project http://openwrt.org
