Fix the broken qdisc instead.

What do you mean? I don't think the qdiscs are broken.
I cannot think of any way how e.g. TBF can do anything useful
with large TSO packets.

Someone posted a patch some time ago to calculate the amount
of tokens needed in max_size portions and use that, but IMO
people should just configure TBF with the proper MTU for TSO.

TBF with 64k atomic units will always be chunky and uneven. I don't
think that's a useful goal.

Then change TBF to use skb_gso_segment?  Be careful, the fact that
one skb ends up queueing multiple skb's would cause issues to parent
qdisc (ie work generating qdisc).
