At least in my world, rates go down as low as 128k.

If this 'qos' sys value is intended to be a generic mechanism to be
used instead of (say) htb,
for more than one type of ethernet device.... I would argue that the
units need to be specified.

Similarly what else is intended to live below the 'qos' subdir?
