There is a qdisc called mq which creates a class for each hardware
queue on
the attached ethernet card. You can bind other qdiscs (such as htb) to
each of
these classes but this will not allow you to shape traffic for a single
type going out over all the hardware queues.
It might be possible to have multiple htb qdiscs and use filters to
send
each type of traffic to a selected hardware queue. This has other
adverse
effects (such as not being able to borrow unused bandwidth among the hw
queues) and there still might be lock contention among the cores for
each such
queue so it might not even work better.
If you are at 1 Gbit speed the cpu can probably handle it so there is
no need
to do any of this. If you have a 10Gbit+ connection then this probably
isn't
the correct place to do shaping anyway and should be done closer to the
source.
It depends on what you're trying to accomplish.
