Make sure kernel doesn't respond to GETs for queues and NAPIs when
link is down. Not with valid data, or with empty message, we want
a ENOENT.

Make sure the netdevsim instance created has a lot of queues, and constrain the size of the recv_buffer used by netlink. While at it test both rx and tx queues.

net: selftest: add test for netdev netlink queue-get API 2024-05-09T01:59:47+00:00 David Wei dw@davidwei.uk 2024-05-07T16:32:28+00:00 1cf2704242180351d156fb48c334b319ae6b0759 Add a selftest for netdev generic netlink. For now there is only a single test that exercises the `queue-get` API. The test works with netdevsim by default or with a real device by setting NETIF. Add a timeout param to cmd() since ethtool -L can take a long time on real devices.
