Series brings the following existing hints to the ice driver: - HW timestamp - RX hash with type Series also introduces new hints and adds their implementation to ice and veth: - VLAN tag with protocol - Checksum level The data above can now be accessed by XDP and userspace (AF_XDP) programs. They can also be checked with xdp_metadata test and xdp_hw_metadata program.
