xDSL (VDSL2) F/OSS implementation

@jow
I dont really understand your answer. The OpenWrt project got some years ago thanks to @hauke ( Hauke Mehrtens ) a free redistributable version. Sadly this is never been updated since. I tried to email haukes publicly known old email address but this seems to not work any more ( hauke.mehrtens@lantiq.com ). So he maybe dont work any more for lantiq and dont have the contacts.
But OpenWrt have some old versions it may be build with and its been build with. Every single xrx200 image include by my knowledge https://mirror2.openwrt.org/sources/dsl_vr9_firmware_xdsl-05.08.01.08.01.06_05.08.00.0B.01.01_osc.tar.gz .
I dont think that lantiq have a problem this days to finally send a redistributable version with vectoring support to the OpenWrt project. The xrx200 chipset is not that much more interesting for the OEM.
As far as i know did OpenWrt not get a vectoring Firmware some years ago because the OEM had to pay for Vectoring support and it would be unfair to give a free version with vectoring without money to OpenWrt. But today this is not important any more.
So Lantiq/Intel, please send an updated version so that we can create images with this firmware file precompiled.

In the meantime: Vectoring DSLAMs normaly allow a 2,2Mhz small connection when a non-vectoring device is been connected to. For the usability the users should get a package they can install with opkg that pulls the DSL-Firmware out of for example the image for the Fritzbox 7490 like described in my howto: Howto: Updating the Lantiq XRX200 devices with latest DSL vectoring firmware

So people install openwrt on their device, connect it and the device itself downloads the most recent DSL firmware from AVM and restarts.

@jow , could you for the usablility add to luci the function to add a firmware file manually? Recently you can do all with luci, just not add an updated firmware file to /lib/firmware/ . Would be great if you could add this functionality.
