This bgmac patch was an attempt to fix/workaround bug reported in https://dev.openwrt.org/ticket/7198 noticed on WNR3500L. Patch assumed length reported by the hardware was 0 and was trying to read it until getting a different value. This was actually the opposite. Lenghts were some invalid & huge values that resulted in skb_over_panic. For example: skbuff: skb_over_panic: text:83b21074 len:57222 (...) skbuff: skb_over_panic: text:87af1024 len:43226 (...) skbuff: skb_over_panic: text:87af5024 len:8739 (...) So instead of that not-working patch checking for 0, write a new one checking for huge values. In case something like that happens, dump hardware state and drop the packet.

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
