Wondershaper should do what you want:

Limit download speed

This is slightly trickier as we can't really influence how fast the
internet ships us data. We can however drop packets that are coming
in too fast, which causes TCP/IP to slow down to just the rate we
want. Because we don't want to drop traffic unnecessarily, we
configure a 'burst' size we allow at higher speed.
Now, once we have done this, we have eliminated the downstream queue
totally (except for short bursts), and gain the ability to manage the
upstream queue with all the power Linux offers.
