I guess it's not only merge and small but big mode as well?

Introduce initial tests for virtio_net driver. Focus on feature testing
leveraging previously introduced debugfs feature filtering
infrastructure. Add very basic ping and F_MAC feature tests.
To run this, do:
$ make -C tools/testing/selftests/ TARGETS=drivers/net/virtio_net/ run
From: Jiri Pirko
The existing setup_wait*() helper family check the status of the
interface to be up. Introduce wait_for_dev() to wait for the netdevice
to appear, for example after test script does manual device bind.

Add a helper to be used to check if the netdevice is backed by specified
driver.

Currently there is no way for user to set what features the driver
should obey or not, it is hard wired in the code.
In order to be able to debug the device behavior in case some feature is

These two check can be done at he very beginning of the script.
As the follow up patch needs to add early code that needs to be executed

This patchset aims at introducing very basic initial infrastructure
for virtio_net testing, namely it focuses on virtio feature testing.
The first patch adds support for debugfs for virtio devices, allowing
