Lorenzo Bianconi b3a54be70c net: ti: cpsw: Add metadata support for xdp mode
Set metadata size building the skb from xdp_buff in cpsw/cpsw_new
drivers. ti cpsw and cpsw_new drivers set xdp headroom at least to
CPSW_HEADROOM_NA:

CPSW_HEADROOM_NA max(XDP_PACKET_HEADROOM, NET_SKB_PAD) + NET_IP_ALIGN

so the headroom is large enough to contain xdp_frame and xdp metadata.
Please note this patch is just compiled tested.
