[Cake] CAKE upstream in LEDE

[Kevin Darbyshire-Bryant]

Dear All,

For those interested, Jonathan Morton's CAKE qdisc has made it into 
LEDE.  See 
https://git.lede-project.org/?p=source.git;a=commit;h=1a3c56f8322d27f4652d23eb7dc14a45e1631e1c 
for proof :-)

The package to install for your target is 'kmod-sched-cake' 
https://downloads.lede-project.org/snapshots/targets/

The base 'iproute2' package has also been taught how to speak 'CAKE' so 
there's no longer any need to install a special version of 'tc' 
(previously supplied by the 'tc-adv' package) 
https://git.lede-project.org/?p=source.git;a=commit;h=23147dd43ac0835cc9077819c32a101dee42461d

Package 'sqm-scripts' has known how to speak 'CAKE' for a while, with 
choices between 'layer_cake' and 'piece_of_cake'.  Also package 
'luci-app-sqm' provides a user friendly web based configuration page for 
'sqm-scripts'

Thanks must go to Hannu Nyman for distilling the relevant changes from 
the sch_cake and tc-adv code repositories 
(https://github.com/dtaht/sch_cake & https://github.com/dtaht/tc-adv) 
into nice, neat patches for LEDE.

It may take a few days for the LEDE build bots to get around to your 
target platform of interest, but the import kernel module 
(kmod-sched-cake) is there.

Enjoy!

Kevin
