Add "ifstat" display:

     ifstat      Display the network traffic going through active interfaces
                 on the system.  Idle interfaces will not be displayed until
                 they receive some traffic.

                 For each interface being displayed, the current, peak and
                 total statistics are displayed for incoming and outgoing
                 traffic.  By default, the ifstat display will automatically
                 scale the units being used so that they are in a human-read-
                 able format.  The scaling units used for the current and peak
                 traffic columns can be altered by the scale command.
