sbin/ipfw ipfw.8 ipfw2.c
sys/netinet ip_dummynet.c
Log:
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.
