The biggest problem was that tcp checksum offload was enabled and used for all hardware, while most of the supported HW (mostly old HW and some newer ones) don't support it. As a result, tcp connections could not be established when using Q-in-Q vlans. This short series corrects this by disabling checksum offload support on packets sent through Q-in-Q vlans. It is up to individual drivers to enable it properly through ndo_features_check if they have some support for Q-in-Q vlans.
