Lorenzo Bianconi 718a18a0c8 veth: Rework veth_xdp_rcv_skb in order to accept non-linear skb ... Introduce veth_convert_skb_to_xdp_buff routine in order to convert a non-linear skb into a xdp buffer. If the received skb is cloned or shared, veth_convert_skb_to_xdp_buff will copy it in a new skb composed by order-0 pages for the linear and the fragmented area. Moreover veth_convert_skb_to_xdp_buff guarantees we have enough headroom for xdp. This is a preliminary patch to allow attaching xdp programs with frags support on veth devices.
