The default speed of normal nic is 1000M while the default speed
of tun is 10M. Now the default speed of tun is changed to 1000M.
And there are 3 options: 10M, 100M and 1000M to the speed of tun.
The command "ethtool -s tun0 speed 10/100/1000" can configure the
speed of tun dynamically.

Why limit to 10/100/1000 speed?
Ethtool speed can be any value

Thanks for your comments.

Yes. But the real physical nic speed often 10M, 100M and 1000M.
This simulates the physical nic.
