Yes and its on by default. The interface mtu still says 1500. I've tried deleting and attaching the qdisc+class (without explicit large mtu) with both tso on (ethtool -K eth0 tso on) and tso off , it doesnt seem to matter - giants appear in both cases. With large mtu for the class no giants with both tso on and off.
