Also, tc doesn't support port-specific operations as that's all handled in a different space of the kernel. Only iptables can do port-specific traffic shaping. You'd have to do something really clever like direct all non port 22 traffic from specified ip to a tap interface off of a bridge and then use tc on that interface, but if you can't mess with iptables without lots of paperwork, I imagine making virtual network adapters public is also not a possibility.
