Restarting Idle Connections

Hi, all.

I have an opinion about net.inet.tcp.initcwnd_segments.
You know, snd_cwnd is restarted transmission after a long idle
period(Current RTO).
And, All of congestion control algorithm is using newreno_after_idle
function after a long idle period.
But, The newreno_after_idle function is not using initcwnd_segments.
I think, The initcwnd_segments should be used in newreno_after_idle
function, If the newreno_after_idle is called.
I referred to rfc6928.

Please check my opinion.
Thank you in advance your answers.
