Hi,

I sent a RFC patch series last year adding multiCPU DSA to upstream
kernel, but the problem is a rather complicated. I plan to try again,
but do not know when.

As for OpenWRT - yes, we will try to add full support for Omnia into
upstream OpenWRT sometime soon. We were waiting for some other
patches to be accepted in upstream kernel.
