52 An XDP program can store individual metadata items into this ``data_meta``
70 Here is the ``AF_XDP`` consumer layout (note missing ``data_meta`` pointer)::
88 the ``data_meta`` pointer.
127 ``AF_XDP`` lacks the ability to communicate the size of the ``data_meta`` area
130 ``xdp_buff->data_meta`` is pointing to ``xdp_buff->data`` before presenting the
139 new xdp_buff->data_meta old xdp_buff->data_meta
153 case, the BPF program should not proceed to populate data into the ``data_meta``
