pf vs. RST attack question

     I'm getting a lot of messages like this:

Oct  4 14:30:00 hellas kernel: Limiting closed port RST response from 250 to 200 packets/sec

Is there some rule I can insert into /etc/pf.conf to reject these apparently
invalid RST packets before they can bother TCP?  At the same time, I do not
want to reject legitimate RST packets.
     Thanks in advance for any clues!
