Currently, page_pool_put_page_bulk() indeed takes an array of pointers
to the data, not pages, despite the name. As one side effect, when
you're freeing frags from &skb_shared_info, xdp_return_frame_bulk()
converts page pointers to virtual addresses and then
page_pool_put_page_bulk() converts them back.
Make page_pool_put_page_bulk() actually handle array of pages. Pass
frags directly and use virt_to_page() when freeing xdpf->data, so that
the PP core will then get the compound head and take care of the rest.
