c. The statistics you want are gathered globally, not per interface.

For me, it prints out the same thing as
netstat -p tcp
This makes sense, given how the statistics are kept, but a) I can't
see how that matches your notion of intended and b) is a bug; using -I
with -p should give an error, since it doesn't print what might
reasonably be expected.
