Description of problem:
When I'm trying to receive small files from tftp server tftp gives me incorrect values about transfer.

Version-Release number of selected component (if applicable):
tftp-0.49-5.1.el6.i686
tftp-server-0.49-5.1.el6.i686

How reproducible:
Always

Steps to Reproduce:
1. Install tftp and tftp-server and change "disable" option to "no" in /etc/xinetd.d/tftp
2. Restart xinetd by "/etc/init.d/xinetd restart"
3. Create a new 10MB file by dd - "dd if=/dev/zero of=/var/lib/tftpboot/10MB bs=1024k count=10"
4. Receive this file and see logs: "tftp <your IP address> -v -c get 10MB"
  
Actual results:
Incorrect numbers like:
Received 10485760 bytes in 7.0 seconds [12069540 bit/s]
Received 10485760 bytes in -2.1 seconds [-39220546 bit/s]
...


Expected results:
Correct statistics
