Now that the IAVF driver simply uses dev_alloc_page() + free_page() with no custom recycling logics, it can easily be switched to using Page Pool / libeth API instead. This allows to removing the whole dancing around headroom, HW buffer size, and page order. All DMA-for-device is now done in the PP core, for-CPU -- in the libeth helper. Use skb_mark_for_recycle() to bring back the recycling and restore the performance. Speaking of performance: on par with the baseline and faster with the PP optimization series applied. But the memory usage for 1500b MTU is now almost 2x lower (x86_64) thanks to allocating a page every second descriptor.
