    sys/netinet          ip_dummynet.c 
  Dummynet has a limit of 100 slots queue size (or 1MB, if you give
  the limit in bytes) hard coded into both the kernel and userland.
  Make both these limits a sysctl, so it is easy to change the limit.
  If the userland part of ipfw finds that the sysctls don't exist,
  it will just fall back to the traditional limits.
  (100 packets is quite a small limit these days. If you want to test
  TCP at 100Mbps, 100 packets can only accommodate a DBP of 12ms.)
  Note these sysctls in the man page and warn against increasing them
  without thinking first.
