Hi, 12.1 kernel with TCP_RFC7413 net.inet.tcp.fastopen.server_enable: 1 net.inet.tcp.fastopen.client_enable: 1 Using code copied from https://people.freebsd.org/~pkelsey/tfo-tools/tfo-client.c I'm not seeing any TFO option on SYN. This is on a loopback connection. Also, it appears to make no difference to the success of the sendto whether or not TCP_FASTOPEN was set on the socket, adding to the confusion. What might I be doing wrong? -- Cheers, Jeremy
