I asume you want each network to use 50% of the bandwith (but they may bo= rrow=20 from each other)? The only thing you have to do is to create 2 new class= es=20 with parent 10:256 , rate =3D 128 and with no bounded parameter. Point t= he 2=20 filters to the 2 new classes and you'r done. And of course, you remove the sfq qdisc from 10:256 and add 2 sfq qdiscs = to=20 the 2 new classes.
