I've prepared a tree rebasing your tree

https://github.com/vladimiroltean/linux/commits/lantiq-gswip/

onto current net-next:

https://github.com/dangowrt/linux/commits/lantiq_gswip-fixes-for-vladimiroltean/

If you don't have time to submit the patches from this tree yourself I
can do that on your behalf, just let me know which of the patches you'd
like to submit as fixes, I'll find the causing commit, add the Fixes:-tag
and send them to netdev@ for the net tree after the next net-next -> net
merge.

Or, in case that makes more sense, send the patches to 'net' now and
then solve the conflicts at the next net-next -> net merge, what ever
works better.
