iproute2: Add support for cake qdisc
Add cake support to 'tc' in iproute2 - Use a patch to modify tc instead of adding a new tc-adv package. Patch creates q_cake.c that matches commit https://github.com/dtaht/tc-adv/commit/3314230bc47328bc9b44faacaad8210065ef98b7 - Do not include the other things from tc-adv (cake0, cake2, pie etc.). V2 - KDB Small update to base on latest cake tc changes (wash option deprecated) V3 - KDB Move kmod-sched-cake package to kernel as is kernel related v4 - KDB Split into individual patches, tc & kmod Signed-off-by: Hannu Nyman <hannu.nyman@iki.fi> Acked-by: Kevin Darbyshire-Bryant <kevin@darbyshire-bryant.me.uk>
