good day, i've been searching for the last while for a way to use
FreeBSD's ipfw and dummynet implementations to limit the number of packets
per second destined for any matching network traffic pipe.  oddly, i can't
find very much information on doing this at all, save for a patch written
in 1999 that i found at:

http://www.geocrawler.com/archives/3/165/1999/3/0/1433347/

"...
       ipfw pipe NNN config pps S

where S is the allowed number of packets per second, and, of course,
other parameters (bw, delay, queue and plr) can be given simultanously.

this of course doesn't seem to actually be in current ipfw though, i tried
it. ;-)

is there some reason limiting packets per second is not an option at the
moment?  or does the capability already exist, and i'm just looking in the
wrong places?  any hints would be appreciated, thanks!
