selftests: net-drv: queues: sanity check netlink dumps
This test already catches a netlink bug fixed by this series,
but only when running on HW with many queues. 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.
