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).
iftop would display portions of mac address with large ffffff prefixes.
Make if_hw_addr type consistent. Kevin Darbyshire-Bryant <kevin@darbyshire-bryant.me.uk>
