[PATCH] ath79: Push MV88E6060 DSA switch into package

[Felix Baumann]

Hi,

I'm pretty certain qca8k is going to be run as a DSA switch eventually, but devs are still working on that to avoid regressions and performance penalties afaik.

There are a couple Pull Requests on github but I can't find the right one at the moment. (some superseeded others)

Regards
Felix Baumann
