I make another test with kernel 4.9.32-15.41
sysctl procps version 3.2.8
sysctl net.ipv4.conf.eth0.100.forwarding
error: "net.ipv4.conf.eth0.100.forwarding" is an unknown key
so I install busybox :
BusyBox v1.19.3
busybox sysctl net.ipv4.conf.eth0.100.forwarding

I wish to suggest to developers to add this new knob :
tcp_retries2_time - INTEGER
This value influences the timeout (seconds) of an alive TCP connection,
when RTO retransmissions remain unacknowledged.
RFC 1122 recommends at least 100 seconds for the timeout,
