Hi! Implement support for tests which require access to a remote system / endpoint which can generate traffic. This series concludes the "groundwork" for upstream driver tests. I wanted to support the three models which came up in discussions: - SW testing with netdevsim - "local" testing with two ports on the same system in a loopback - "remote" testing via SSH so there is a tiny bit of an abstraction which wraps up how "remote" commands are executed. Otherwise hopefully there's nothing surprising. I'm only adding a ping test. I had a bigger one written but I was worried we'll get into discussing the details of the test itself and how I chose to hack up netdevsim, instead of the test infra... So that test will be a follow up :) --- TBH, this series is on top of the one I posted in the morning: https://lore.kernel.org/all/20240412141436.828666-1-kuba@xxxxxxxxxx/ but it applies cleanly, and all it needs is the ifindex definition in netdevsim. Testing with real HW works fine even without the other series.
