Joshua Washington says:

====================
XDP metadata support for DQ RDA

This small series enables XDP metadata support in DQ RDA mode. While
space is reserved in the headroom for metadata and the DQ queue format
supports the xmo_rx_timestamp metadata operation, support for adjusting
the metadata and passing metadata along to SKBs was not actually
implemented.
