You might also want to add this field, from NetBSD:

         u_long          bd_ccount;      /* number of packets captured */

Note that a matched packet does not mean it gets captured.

I suppose you could argue that:
fcount - dcount = ccount

In general, I don't care how many packets have matched the filter but
what I do care about is how many get dropped and how many are captured.

I think I talked about this first here:

but I can't be sure because the "great firewall of china" seems to be
blocking access to it.
