Merge branch 'bpf: expose information about netdev xdp-metadata kfunc support'
Stanislav Fomichev says:
====================
Extend netdev netlink family to expose the bitmask with the
kfuncs that the device implements. The source of truth is the
device's xdp_metadata_ops. There is some amount of auto-generated
netlink boilerplate; the change itself is super minimal.
v2:
- add netdev->xdp_metadata_ops NULL check when dumping to netlink (Martin)
