  Try netstat -i -b (as documented in the man page)!  For a
single interface, use "netstat -b -I <iface>".  Here's sample output:

% netstat -ib
Name  Mtu   Network       Address               Ibytes     Obytes
we0   1500  <Link>        00:00:c0:84:84:8b  539467677  255418727
we0   1500  128.83.52/24  marvin.ece.utexas  539467677  255418727
lo0   32976 <Link>                            17356832   17356832
lo0   32976 your-net      localhost           17356832   17356832
...

% netstat -b -I we0
Name  Mtu   Network       Address               Ibytes     Obytes
we0   1500  <Link>        00:00:c0:84:84:8b  540102217  255929648
we0   1500  128.83.52/24  marvin.ece.utexas  540102217  255929648
