From c7203a2981dcd0aa738312a458317d86037a69e7 Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Thu, 13 Jul 2023 18:15:31 +0200 Subject: [PATCH] selftests: router_bridge: Add tests to remove and add PVID This test relies on PVID being configured on the bridge itself. Thus when it is deconfigured, the system should lose the ability to forward traffic. Later when it is added again, the ability to forward traffic should be regained. Add tests to exercise these configuration changes and verify results. Signed-off-by: Petr Machata Reviewed-by: Danielle Ratson Signed-off-by: David S.
