selftests: mptcp: decrease BW in simult flows
When running the simult_flow selftest in slow environments -- e.g. QEmu without KVM support --, the results can be unstable. This selftest checks if the aggregated bandwidth is (almost) fully used as expected. To help improving the stability while still keeping the same validation in place, the BW and the delay are reduced to lower the pressure on the CPU. Fixes: 1a418cb8e888 ("mptcp: simult flow self-tests") Fixes: 219d04992b68 ("mptcp: push pending frames when subflow has free space") Cc: stable@vger.kernel.org Suggested-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: Matthieu Baerts (NGI0) <matttbe@kernel.org> Link: https://lore.kernel.org/r/20240131-upstream-net-20240131-mptcp-ci-issues-v1-6-4c1c11e571ff@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
