[PATCH iwl-next v1 0/3] i40e: support XDP metadata ops (RX

[Kohei Enju <kohei@enjuk.jp>]

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.

  i40e: prepare for XDP metadata ops support
  i40e: add support for bpf_xdp_metadata_rx_hash()
  i40e: add support for bpf_xdp_metadata_rx_vlan_tag()
