Cover letter [PATCH v2 net-next 0/2] add page_pool support for page recycling in veth driver

Introduce page_pool support in veth driver in order to recycle pages in veth_convert_skb_to_xdp_buff routine and avoid reallocating the skb through the page allocator when we run a xdp program on the device and we receive skbs from the stack.

Change since v1:
- remove page_pool checks in veth_convert_skb_to_xdp_buff() before allocating the pages
- recycle pages in the hot cache if build_skb fails in veth_convert_skb_to_xdp_buff()
