I only did a quick grep around the driver so i might be missing something,
but i can only see allocations via napi_alloc_frag(). XDP requires pages
(either a single page per packet or a driver that does the page management of
its own and fits 2 frames in a single page, assuming 4kb pages).
Am i missing something on the driver?

As Jesper said we are doing similar work on a cortex a-53 and plan to work on
a-72 as well. We might be able to help out.
