The primary goal is to add test validation for GSO when operating over UDP tunnels, a scenario which is not currently covered.
The design strategy is to extend the existing tun/tap testing infrastructure to support this new use-case, rather than introducing a new or parallel framework. This allows for better integration and re-use of existing test logic.
--- v3 -> v4: - Rebase onto the latest net-next tree to resolve merge conflicts.
v3: https://lore.kernel.org/netdev/cover.1767580224.git.xudu@redhat.com/ - Re-send the patch series becasue Patchwork don't update them.
v2: https://lore.kernel.org/netdev/cover.1767074545.git.xudu@redhat.com/ - Addresse sporadic failures due to too early send. - Refactor environment address assign helper function. - Fix incorrect argument passing in build packet functions.
