From 0e07d5dbfbd9b0441ae4ec07a2a72738121356e2 Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Thu, 17 Oct 2024 11:45:45 +0200 Subject: [PATCH] selftests: forwarding: lib: Allow passing PID to stop_traffic() Now that it is possible to schedule a deferral of stop_traffic() right after the traffic is started, we do not have to rely on the %% magic to kill the background process that was started last. Instead we can just give the PID explicitly. This makes it possible to start other background processes after the traffic is started without confusing the cleanup.
