sysctl_createv(clog, 0, NULL, NULL,
		CTLFLAG_PERMANENT|CTLFLAG_READWRITE,
		CTLTYPE_STRING, "selected",
		SYSCTL_DESCR("Selected Congestion Control Mechanism"),
		sysctl_tcp_congctl, 0, &tcp_congctl_global_name, 0,
		CTL_NET, pf, IPPROTO_TCP, congctl_node,
		CTL_CREATE, CTL_EOL);

should be:

		sysctl_tcp_congctl, 0, NULL, TCPCC_MAXLEN,

yes, our sysctl is too cryptic.
