I build another OpenWrt image and it doesn't work. I don't know why and it's difficult to add modifications into OpenWrt kernel, because the kernel sources don't persist. The build system erases everything, unpacks fresh kernel sources and then patches them. To make any modification I have to add .diff files into the patches dir and build again, write the new firmware into the router flash, test, etc. It's very slow. I think I'm going to leave it as it is and limit the speed from the kernel command line until OpenWrt updates the kernel. Thank you for your help. Marius Dinu
