The intent is to upstream the entire suite of the DPAA drivers. All the
drivers are still WIP, but B/QMan have been already presented to the
upstream community and this is the first attempt to publish (some low
level code of) the FMan driver. As we go through our internal checklist
and in the same time address community feedback we'll soon get the
drivers to be acceptable for the upstream trees

The first version of the actual Ethernet driver will follow imminently

SDK enablement is a side-effect

Both. Full DPAA/Ethernet enablement will be present in the kernel. We
also have support for user-space based approach. I'm unsure where/when
we might publish that. Of course the SDK is always a place you can turn
to for all the code we have (in whatever state it might be)
