Flaky test: TestRunContainerWithBridgeNone #37246
Description
For example, https://jenkins.dockerproject.org/job/Docker-PRs-experimental/40976/console (#37172)
Looks like there's a race in this test, because it compares network interfaces on the host with network interfaces inside the container; if interfaces are removed between checking both (e.g. due to other containers being spun up), comparisson wil fail, and thust the test
