tcp: /proc/net/tcp rto,ato values not scaled properly (v2)
I found another case where we are sending information to userspace
in the wrong HZ scale. This should have been fixed back in 2.5 :-(
This means an ABI change but as it stands there is no way for an application
like ss to get the right value.
