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 :)
v3: - first two patches are new - make Remote::cmd() return Popen() object (patch 3) - always operate on absolute paths (patch 3) - last two patches are new v2: https://lore.kernel.org/all/20240416004556.1618804-1-kuba@kernel.org - rename endpoint -> remote - use 2001:db8:: v6 prefix - add a note about persistent SSH connections - add the kernel config v1: https://lore.kernel.org/all/20240412233705.1066444-1-kuba@kernel.org
