A net device has a threaded sysctl that can be used to enable threaded
napi polling on all of the NAPI contexts under that device. Allow
enabling threaded napi polling at individual napi level using netlink.

Extend the netlink operation `napi-set` and allow setting the threaded
attribute of a NAPI. This will enable the threaded polling on a napi
context.

Tested using following command in qemu/virtio-net:
./tools/net/ynl/cli.py --spec Documentation/netlink/specs/netdev.yaml \
  --do napi-set       --json '{"id": 66, "threaded": 1}'

Is there a sane way for a 'real person' to set these from a normal
startup/network configuration script?

The netlink API is hardly user-friendly.

There is a C library, libynl that abstracts a lot of the netlink
stuff away and is quite nice. That said, if you wanted to use it
from a script, you'd probably need bindings for it in the language
of your choice.

If you meant more a shell script type setup, then yea.... the python
CLI is (AFAIK) the only option.
