Since we have software fallbacks in case the NIC can not handle some features for multiple vlans, we can add the same features as the lower vlan devices for stacked vlan devices. This allows stacked vlan devices to create large (GSO) packets and not to segment packets. Those packets will be segmented by software on the real device, or even can be segmented by the NIC once TSO for multiple vlans becomes enabled by the following patches. The exception is those related to FCoE, which does not have a software fallback. Signed-off-by: Toshiaki Makita Signed-off-by: David S. Miller --- Reading git-diff-tree failed
