There's already a reusable FQ structure in the kernel (which is what the WiFi stack uses), which is partially modelled on Cake's tins. I had half a mind to try to have the two converge; Cake would shed some LOCs, and the WiFi stack could get set-associativity... -Toke _______________________________________________ Cerowrt-devel mailing list [email protected] https://lists.bufferbloat.net/listinfo/cerowrt-devel
