Then it's better to create a separate class for it and put your ssh traffic in
it.

Incoming traffic can be tricky. You need the imq device or a dedicated shaper
for it so you can shape on 2 nic's.

The problem is not marking with iptables, but shaping. If you add something
to nic eth0, you shape outgoing packets for that nic. You can not do this
for incoming packets. What you can do is use imq. This is a virutal device
and you can redirect incoming packets to it. And you can add a htb qdisc to
it .... Or you have to use filters + policers, but that's not powerful.

The exceed is normal. Traffic is bursty and you can not expect to shape it
perfectly.

Then you have a problem. You can not configure this with htb because you
don't know the ISP bandwidth. However, you can create a setup for 1024 kbps.
You will loose some precision because you are not the bottleneck anymore, but
you will able to shape your link.
