 	OK. Long ago the idea was ipvsadm to change the
timeouts for all states but it was not finished. IIRC,
all sysctl vars to control these timeouts are disabled.
What is missing is some method (via netlink) to provide
protocol, state name and timeout to the tcp_set_state_timeout
function because some users want to reduce the memory
usage with lower timeouts. Example:

# ipvsadm --get-proto-timeouts TCP SYN_RECV,ESTABLISHED
TCP.SYN_RECV=60
TCP.ESTABLISHED=900

# ipvsadm --set-proto-timeouts TCP "SYN_RECV=10, ESTABLISHED=20"
