[Cake] resubmitting cake for 4.16

[Dave Taht]

After taking some time off.. and... after a few bug fixes (of problems
introduced by me, sorry all), and much panic'd exploration of gcc 7.3
retpolines and spectre/meltdown later... it looks like we could,
indeed, try to get cake upstream again after net-next reopens in 2-3
weeks.

After catching up on my mail, the only thing that still looks shaky
was the hard_header_len controversy (?)
