Subject: [PATCH bpf-next 0/3] bpf: expose information about netdev xdp-metadata kfunc support
Date: Fri, 8 Sep 2023 15:58:04 -0700 [thread overview]
Message-ID: <20230908225807.1780455-1-sdf@google.com> (raw)
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.
