The page_pool API has no users for it's DMA capabilities yet. Retrieving DMA addresses used by network drivers will be needed for real users. commit 1567b85eb8ad ("net: page_pool: don't use page->private to store dma_addr_t") uses 'struct page' to store the addresses. This patch provides a helper for retrieving them.
