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

Message

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()
