Subject: Purpose of bit shifts in tcp_get_info

Dear Community,

I was wondering what the purpose of the bit shifts in tcp_get_info  
right after the jiffies conversion might be. What's the time unit  
after that shift?

         info->tcpi_rtt = jiffies_to_usecs(tp->srtt)>>3;
         info->tcpi_rttvar = jiffies_to_usecs(tp->mdev)>>2;
[...]
         info->tcpi_rcv_rtt = jiffies_to_usecs(tp->rcv_rtt_est.rtt)>>3;

Maybe somebody has a hint for me?

Thanks a lot!
Daniel
