32  * This test is to ensure that if TCP Fast Open is configured, that socket
33  * connections will still work. These tests are able to detect if TCP Fast
41  * The second test will create the TCP fast open cookie,
43  * e.g. on Linux 4.15.0-135-generic:
44  * $ grep '^TcpExt:' /proc/net/netstat | cut -d ' ' -f 84-90 | column -t
45  * The third attempt will use the cookie and actually do TCP fast open.
46  * The 4th time is client-TFO only, the 5th time is server-TFO only.
