[PATCH wireguard-tools v3 0/3] ipc: linux: kernel-side netdevice filtering

[Asbjørn Sloth Tønnesen]

Move device filtering to the kernel, thereby reducing netlink traffic.

The first patch request kernel-side filtering.

The second patch requests that the kernel doesn't include statistics
in netdevice dumps.

The third patch removes the old filtering code, as an
additional step, which breaks on earlier than Linux v4.6.

I assume that a dependency on Linux v4.6+ is acceptable for wg-tools
now, as wireguard-linux-compat haven't been updated for 3 years.
