SubjectAsk some help for the netstat Send-Q
Date
Hi David S. Miller and maintainers:

I use the 4.1.16 kernel to build my system and use the iperf to test the netstat, it looks very strange that the client shows:

netstat -at | grep 10.175.112.105
tcp 0 0 10.175.112.191:ssh 10.175.112.105:58400 ESTABLISHED
tcp 0 0 10.175.112.191:33230 10.175.112.105:5001 TIME_WAIT
tcp 0 4202096 10.175.112.191:33231 10.175.112.105:5001 ESTABLISHED
tcp 0 0 10.175.112.191:ssh 10.175.112.105:58335 ESTABLISHED

and the speed is:
[ 3] 0.0-300.0 sec 32.5 GBytes 929 Mbits/sec

It looks like that the speed is fine, But I don't know why the Send-Q has so many buffers,
the tcp_wmem is big enough and I couldn't found any difference, did I miss something or
is there something wrong for the TCP config?
Thanks for any suggestion.

Ding
