dd-wrt has it already :-)

Unfortunately some targets in openwrt are still on 4.14 kernels so there is no in-tree CAKE to use.  Dropping CAKE from pre 4.19 kernels caused a bit of an outcry when I did it, so the next idea was to have a choice of cake kernel module for K4.19 targets, in-tree & out-of-tree CAKE.  Unfortunately that exposed a weakness in package dependency selection, so that idea hasn’t flown either.  I’m afraid enthusiasm levels then dropped.
