Lorenzo Bianconi says:

====================
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.
