Subject: [PATCH] vlan: allow TSO setting on vlan interfaces

When we need to shape traffic with low speeds, we need to disable tso on
network interface :

ethtool -K eth0.2240 tso off

It seems vlan interfaces miss the set_tso() ethtool method.
Propagating tso changes from lower device is not always wanted, some
vlan want TSO on, other want TSO off.
