This series adds support for XDP metadata ops. Since the i40e RX timestamps are not available from the RX descriptor in the XDP path, this series doesn't implement bpf_xdp_metadata_rx_timestamp().
Patch 1/3 prepares i40e_xdp_buff for subsequent patches. Patch 2/3 and 3/3 introduce bpf_xdp_metadata_rx_hash() and bpf_xdp_metadata_rx_vlan_tag() respectively. Tested on Intel Corporation Ethernet Controller X710 for 10GbE SFP+ with ./tools/testing/selftests/bpf/xdp_hw_metadata. Since i40e doesn't support HWTSTAMP_FILTER_ALL as an rx_filter, I locally changed the selftest to use HWTSTAMP_FILTER_NONE instead.
