* Some tools, such as `tcpdump` and old versions of `ping`, require explicitly
enabling raw sockets via the unsafe `--net-raw` runsc flag.
+ * In case of tcpdump the following invocations will work

+ * tcpdump -i \<device-name\> -p (-p disables promiscuous mode)
* Different Docker images can behave differently. For example, Alpine Linux
and Ubuntu have different `ip` binaries.
