There are a few timing constraints the we struggle to meet on very slow environments. Instead of skipping the whole tests in such envs, increase the test resilience WRT very slow hosts: increase the inter-packets timeouts, avoid resetting the counters every second and finally disable reduce the background traffic noise. Tested with: for I in $(seq 1 100); do ./tools/testing/selftests/kselftest_install/run_kselftest.sh \ -t net:udpgro_fwd.sh || exit -1 done in a slow environment.
