net: mvpp2: Add metadata support for xdp mode
Set metadata size building the skb from xdp_buff in mvpp2 driver
mvpp2 driver sets xdp headroom to:
MVPP2_MH_SIZE + MVPP2_SKB_HEADROOM
where
MVPP2_MH_SIZE 2
MVPP2_SKB_HEADROOM min(max(XDP_PACKET_HEADROOM, NET_SKB_PAD), 224)
so the headroom is large enough to contain xdp_frame and xdp metadata.
Please note this patch is just compiled tested.
