Our page_pool API already has recycling capabilities that are always used when we are running in 'XDP mode'. So let's tweak the API and the kernel network stack slightly and allow the recycling to happen even during the standard operation. The API doesn't take into account 'split page' policies used by those drivers currently, but can be extended once we have users for that. The idea is to be able to intercept the packet on skb_release_data(). If it's a buffer coming from our page_pool API recycle it back to the pool for further usage or just release the packet entirely. To achieve that we introduce a bit in struct sk_buff (pp_recycle:1) and store the page_pool pointer in page->private. Storing the information in page->private allows us to recycle both SKBs and their fragments. The SKB bit is needed for a couple of reasons. First of all in an effort to affect the free path as less as possible, reading a single bit, is better that trying to derive identical information for the page stored data. Moreover page->private is used by skb_copy_ubufs. We do have a special mark in the page, that won't allow this to happen, but again deciding without having to read the entire page is preferable. The driver has to take care of the sync operations on it's own during the buffer recycling since the buffer is, after opting-in to the recycling, never unmapped. Since the gain on the drivers depends on the architecture, we are not enabling recycling by default if the page_pool API is used on a driver. In order to enable recycling the driver must call skb_mark_for_recycle() to store the information we need for recycling in page->private and enabling the recycling bit, or page_pool_store_mem_info() for a fragment. Since we added an extra argument on __skb_frag_unref() to handle recycling, update the current users of the function with that.

The test was done by sending to the macchiatobin 64 byte ethernet frames with an invalid ethertype, so the packets are dropped early in the RX path.
