The mvneta controller is able to do some tocken-bucket per-queue traffic
shaping. This commit adds support for setting these using the TC mqprio
interface.

The token-bucket parameters are customisable, but the current
implementation configures them to have a 10kbps resolution for the
rate limitation, since it allows to cover the whole range of max_rate
values from 10kbps to 5Gbps with 10kbps increments.

Breaks 32bit build, please make sure you use division helpers for 64b.

My bad, I'll update to use the proper helpers then (and compile-test
for 32bits this time too, sorry about that)

Thanks,

Maxime
