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:

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
