The only needed way for this is just feeling to have a solution integrated. Since 9.0 dummynet can be loaded without ipfw(4) and ipfw(8) tool can be used for it. > I have managed to integrate ipfw/dummynet.c into pfctl and it all > seems to work for me - except that flows are not persistent so that > my statistics doesn't work. =A0I am still working through to see if > this is something I broke or a new "feature". > > I hope to forward patches once I'm happy with it. > >>To me something that is glued on ipfw should stay there as it will get >>the best support. >>Possibly splitting dummynet configuration out to dnctl might have an argu= ment. > > IMHO, it would be a great improvement to separate dummynet from ipfw. > As a start it is very easy to separate dummynet functions from ipfw(8) and come up with a dnctl utility. Later on it can be improved. Just that a big warning would have to be put on ipfw(8) to let many people aware of this. This IMHO would be worth spending time on if you really want to feel dummynet as its own solution. It is not a very big job per se as well.
