[Intel-wired-lan] [PATCH net-next 00/10] Call skb_metadata_set when skb->data points past metadata

[Jakub Sitnicki]

This series is split out of [1] following discussion with Jakub.

To copy XDP metadata into an skb extension when skb_metadata_set() is
called, we need to locate the metadata contents.

These patches establish a contract with the drivers: skb_metadata_set()
must be called only after skb->data has been advanced past the metadata
area.
