bpf, i40e: add meta data support
Add support for XDP meta data when using build skb variant of
the i40e driver. Implementation is analogous to the existing
ixgbe and ixgbevf support for meta data from
366a88fe2f40 ("bpf,
ixgbe: add meta data support") and
be8333322eff ("ixgbevf: Add
support for meta data"). With the build skb variant we get
192 bytes of extra headroom which can be used for encaps or
meta data.
