[Cake] cake work needed for openwrt merge

[Dave Taht]

In discussing with felix what is needed for cake to go into openwrt
trunk, we came up with the following list:

* Cake work needed
** Add squash option (besteffort + squashing diffserv)
** Fix diffserv
** Add man page
** Clean up patches to only do cake
*** Reformat for kernel_style
*** IProute patches for mainline iproute
** Submit as a single patch to openwrt for each
** cake patches goes into the openwrt iproute directly
** continues to be built externally as kmod-sched-cake
** Needs update to the new kernel hashing api
** Openwrt is stablizing for now, on linux 4.1
** CC is essentially done, but there will a CC.1 release at some point
** Add better statistics (like active_flows) - have part of this already
