Hi Damien,

Thanks for reply, I think that's expected behavior when we set timeout
based rekey value, that timer based rekey should happen regardless of
traffic. 

It was working fine before following commit: 

https://github.com/openssh/openssh-portable/commit/21da87f439b48a85b951ef1518fe85ac0273e719

As before that, server was sending keep alive signals at rekey timeout
which produce traffic and rekeying start happening.

Than, I see a fix from upstream related to this:   
https://github.com/openssh/openssh-portable/commit/073f45c236550f158c9a94003e4611c07dea5279#diff-6e5958092d48b108bef3faadd24f2259a7e999ba8771cb64c986179c059fe130

But, even this fix didn't solve the issue, as there is a check for
traffic that's preventing rekeying.

Sorry due to account issues created another Pull request,
https://github.com/openssh/openssh-portable/pull/373
