Option to display packet counts - Frédéric Perrin <email@example.com>
Add a "-u unit" CLI option, as well as a "bandwidth-unit" configuration file option. With "-u packets", traffic is accounted using packets per second; the other options are "-u bits" and "-u bytes". "-B" is still recognized as synonym to "-u bytes". The default is "-u bits", keeping the current behaviour of iftop (everything is in bits/s, except the cumulative totals).
