thanks, and is it possible to take those patches and apply them to mainline? is this supposed to happen or is there something that blocks that? i would love to use latest official openwrt on that device. I also noticed they use v21.xx, oldstable is v22. Are there any security related issues? Is v21 even still supported?

edit: i got an answer and it seems like they try to release a 23.x version and in 1-2 weeks there should be support for openwrt in snapshot. would be great.
