I really really wished cake would report the packet size before and _after_ its overhead addition making sanity checking much easier. BTW tc's stab might be useful as an external check... I also wonder whether the kernel's behaviour in regards to ppp interfaces changed between kernel 4.4 and newer ones, I see the same weirdness:
FWIW my pppoe router/pvr/nas box is running 4.1.46. It's a bay-trail dc
board and they are prone to cstate bug locks, which is why I'm not
running anything newer!
